Feedback on your own drawing
Rate my drawing —honest feedback, drawn right on your sketch.
Upload a photo or draw here to get Luna’s AI feedback on your sketch, with technique notes, suggested changes and a practice exercise. Check your remaining free allowance and options for additional critiques before you submit.
Luna measures technique — never your creativity or style.
Add a photo of your sketch
Photograph your drawing in good light and fill the frame with the drawing. Pencil, ink or marker are all fine.
How the sketch critique works
Draw a sketch and get feedback on it! We will give you feedback on your technique as well as some suggestions to improve. Also, you will get to choose one of the corrections to practice.
Show Luna your sketch
Please upload a clear photo or screenshot of your attempt, or simply draw it on the provided canvas! If you used a reference, please include a copy of it as well. Does not have to be completed!
Review the feedback on your drawing
Compare the technique scores with the notes marked on your sketch. It is easy for AI to misread details.
Choose one thing to practise
Complete the suggested exercise or implement one important change, and return to your drawing to see where that practice has helped.
What the five scores measure
Concrete, practiceable technique — never creativity, style, or subject choice.
Lines
Are your strokes confident and continuous, or stitched from short, hesitant marks? This part of the feedback looks at the linework.
Shading
Are your values (tone) even and deliberate? Do the pressure, direction and edges support the form? Muddy values can make a shaded form hard to read; an intentionally unshaded drawing can still be complete.
Corners & Joins
Are the strokes joining at the correct places on your drawing or are they overshooting and leaving gaps?
Precision
Do your marks land where you aimed them? Precision is trainable.
Proportions
Are the sizes of the forms and the placements correct in relation to each other? Your eye is going to pick up on a proportion error before you can even name it. By adding the reference that you drew from to your scored drawing, this score will indicate how well your drawing matched the reference.
The skills you need to improve are all trainable. The critique above outlines which you need to work on. the free drawing exercises train four of the five with a number after every attempt — scored in your browser, unlimited tries — and the Sketching Essentials coursethen builds your skills step by step with AI feedback at drawing checkpoints — orbrowse all courses. If you want the theory behind this feedback-first approach, read our guide to deliberate practice for drawing.
Compare to your reference
Drawing from a reference? See how close you got
So long as you include a reference (i.e. study, copy of a master, drawing from a photo of a scene etc), then you can get feedback on how well you have copied the key proportions, placement, angles etc of the subject. It can highlight places where your drawing differs from the reference, giving you something specific to check. Compare the suggestion with your goal, especially if you changed a proportion on purpose.
- Proportion and accuracy measured against your actual reference
- Corrections drawn on your drawing, never on the reference
- Completely optional — skip it for a technique-only critique
“Next to your reference, the head reads a little large and the shoulders sit narrower than the photo — nudge the shoulder line out and the likeness snaps into place.”
A real reference comparison, in Luna's words
Get a drawing critique that's actually useful
Remember that the best feedback Luna can give you is based on what she can see in the photo of your drawing. Take a photo of your drawing in good, even lighting, with the drawing filling the frame. The tool can straighten a tilted page, but it cannot recover hidden parts of the drawing or fix every camera angle. Keep the whole page visible, avoid glare and very dark shadows, and check the prepared image. Pencil, ink, charcoal and even marker sketches all read just fine.
Note that if you did a study from reference (photo, still life, master study) you can upload the reference as well and Luna can suggest places where your shapes and proportions deviate from the source. But that’s up to you, otherwise Luna will simply judge your technique based on the drawing itself.
Most important of all, you don’t have to send in a finished piece of work. A work-in-progress critique can be even more useful, because you can apply the feedback before you’ve invested too much time in a piece that’s not quite right. One useful practice is to submit work, apply a relevant fix, and then try another drawing. Watching your scores move from Fair to Good on a single aspect of drawing will help you to understand very quickly just what you have learned about how to improve your drawings.
When a drawing feels wrong in a way you cannot name, one of these five areas can give you a place to start looking. A critique may point out something useful, and you can compare that suggestion with the drawing yourself.
What a sketch critique looks like
Critique of simple mug sketching: Notes are circled on the drawing, 5 scores, 1 fix for the sketching, and 1 exercise for further development.
A note is placed near the part it discusses, such as the side of the mug where the line needs to be more continuous. The radar chart shows the technique scores together, while the written notes explain what to check. The summary will read like the margin notes of a teacher’s copy of your drawing: first what you did well and then what you need to do to improve.

Feedback for your next drawing
Luna analyzes your sketch and proposes things for you to check. Based on that you decide what changes you need to make to your drawing. Our learning materials as well as the AI feedback provided here are meant to support your learning. The drawing and the decisions are yours.
Rate my sketch: frequently asked questions
Is sketch feedback free?+
As mentioned, you can use the tool for free without opening an account. In this case, you will first see how much you can use for free before you have to submit your drawing for feedback. Also, the drawing exercises remain free and unlimited as always.
What can I submit?+
Upload a photograph of your pencil, ink, charcoal or marker sketch. This can also be drawn directly within the browser and left unfinished as a study. Use a clear, well-lit image so the lines and any shading are visible. The drawing can be unshaded or unfinished.
What happens to my uploaded drawing?+
Once you have uploaded an image of your drawing it will be analyzed and annotated with feedback for you. Uploaded images are deleted from our servers within 30 days, and your drawings are not used to train AI models. The feedback you receive is for your information only and you can use it or not as you choose. We suggest you download a copy of the score card so you can keep a copy of the feedback given to you.
What do the scores tell me?+
A score card contains feedback on lines, on shading, on corners and joins, on precision and on proportions. You can use this feedback as tips for practice or for observing your technical development. The feedback is NOT an objective rating of your creativity, your personal style or your artistic value.
How should I use the feedback?+
For each observation suggested by the AI, you compare it against your own work and decide whether it is useful or not. Practise one adjustment on a separate drawing and continue the process. Not all observations will be of equal value. You don’t have to accept every point or strive for a perfect score.
Can I include a reference image?+
Yes, you can upload a reference for your sketch, like a photograph or another image you drew from. The reference gives context for placement, proportions and shapes. It is optional, and you can also get feedback on an original drawing without one.
Can I photograph a page at an angle?+
The upload flow can straighten a tilted page before analysis. Start with a clear photo, and make sure the whole drawing is visible in the prepared image. Check it carefully if the paper is curled, partly hidden or strongly shadowed.
Does it support cartoons and stylized drawings?+
You can submit cartoons, anime and other stylized drawings. The feedback aims to take into account the style and subject matter that you provided for analysis. If a suggested correction will undo an exaggeration or feature that you had intentionally included in the piece, then you can choose to disregard that feedback in favor of keeping the work as it is in relation to your overall goals for the piece.
How does this connect to lessons and exercises?+
For using sketch feedback to select work to do with your drawing, an exercise isolates a skill and a tutorial uses that skill to complete a drawing. Guided courses add the value of having drawing demonstrations and feedback at each step of your progress with your drawing.
