Free drawing critique
Rate my sketch — honest feedback, drawn right on your drawing.
Upload a photo of your sketch, or draw here in the browser. Luna — a coach that checks your work — scores five skills, circles what to fix right on your drawing, and shows you why it looks off. About 20 seconds.
Luna measures technique — never your creativity or style.

Tip: photograph your sketch in good light and fill the frame with the page. Pencil, ink, or marker all work.

How the sketch critique works
This is a rate-my-drawing tool with reasons, not just a score. Every critique follows the same three steps and takes about 20 seconds end to end.
Show Luna your sketch
Photograph a pencil, ink, or marker drawing straight from your sketchbook, paste a screenshot, or draw on the built-in canvas. Work-in-progress is welcome — no account needed.
She measures five skills and marks up your drawing
You get a score for lines, shading, corners & joins, precision, and proportions — plus up to three notes circled directly on the drawing, exactly where the issue lives.
You leave with one fix and one exercise
Instead of ten vague tips, the critique names the single highest-leverage fix and a five-minute practice drill matched to your weakest skill. Redo it and re-check to watch the scores move.
What the five scores measure
Concrete, practiceable technique — never creativity, style, or subject choice.
Lines
Are your strokes confident and continuous, or feathered and re-drawn? A low score usually means lines stitched from short, hesitant marks.
Shading
Is your tone even and deliberate — pressure, direction, edges? Flat or muddy values are the most common reason a drawing reads as unfinished.
Corners & Joins
Do strokes meet cleanly where they should, or overshoot and gap? Open joins quietly make a structure feel unstable.
Precision
Do your marks land where you aimed them? Precision is trainable accuracy, not neatness.
Proportions
Do the sizes and placements agree with each other? Your eye notices a proportion error before you can name it.
Every one of these skills is trainable. The critique tells you which one to work on; the Sketching Essentials course then builds it step by step with the same coach checking every attempt — or browse all courses. If you want the theory behind this feedback-first approach, read our guide to deliberate practice for drawing.
Get a drawing critique that's actually useful
The feedback is only as good as what Luna can see. Photograph your sketch in even light, fill the frame with the page, and avoid glare or strong shadows — she is trained to ignore notebook lines, paper texture, and camera angle, but she can't score what's hidden. Pencil, ink, charcoal, and marker all work.
You don't need a finished piece. A work-in-progress critique often helps more, because you can apply the fix before investing another hour. The habit that improves people fastest: submit, apply the one fix, redraw, and submit again — watching a score move from Fair to Good teaches your eye what the difference feels like.
And if your drawings keep looking wrong in a way you can't name, that feeling is almost always one of the five measurable skills above — not missing talent. A critique points at the exact spot instead of leaving you guessing.
What a sketch critique looks like
A real critique of a simple mug sketch: notes circled on the drawing, five scores, one fix, one exercise.
Each note is anchored to the exact spot it talks about — "draw this side in one slower stroke" means this side, not lines in general. The radar shows all five scores at a glance, and the summary reads like a teacher's margin note: what works first, then the one thing to fix.

Rate my sketch: frequently asked questions
Is this drawing critique really free?+
Yes — no account, no card. Your first critique starts right on this page, and every visitor gets about three per day. The full course behind it has a free first lesson too; we'd rather earn you than wall you.
What kind of drawings can I submit?+
Photos of pencil, ink, charcoal, or marker sketches, or anything you draw on the built-in canvas. Photograph your page in good light and fill the frame for the most accurate feedback. Unfinished, work-in-progress sketches are welcome.
What happens to my drawing after the critique?+
It is analyzed, annotated, and automatically deleted from our servers within 30 days. Nothing is generated from it, and your drawings never train AI models — ever. The score card you download is yours to keep.
How do I know if my drawing is good?+
"Good" is subjective, but technique is measurable. Instead of a yes-or-no verdict, the critique scores five concrete skills — lines, shading, corners and joins, precision, and proportions — so you can see which one is holding a drawing back and which are already strong.
Why does my drawing look off even when I can't say why?+
That feeling almost always traces to one of five measurable causes: hesitant line quality, proportions that disagree with each other, flat values, strokes that miss their joins, or marks that don't land where you aimed. A critique points at the exact spot instead of leaving you guessing.
What do the five scores measure?+
Lines, Shading, Corners & Joins, Precision, and Proportions — concrete, practiceable technique. Luna never scores creativity, style, or subject choice, because those aren't hers to grade.
Is this an AI art critique tool?+
Luna uses a vision model to measure technique, the way a chess app analyzes your moves. Nothing is ever generated, nothing is drawn for you, and your work never trains any model — that pledge is published on this page. We think of her as a coach that checks your work.
How is this different from posting on Reddit or a critique forum?+
Forums are wonderful but slow, public, and inconsistent — replies can take days and range from a careful redline to "looks nice." Here you get private, structured feedback in about 20 seconds, with notes drawn on the drawing itself, and you can re-check a redo immediately.
How is this different from other rate-my-art tools?+
Most rate-my-art tools return a paragraph of generic praise about a photo of your art. Luna marks up your actual drawing with circles and notes, scores five specific skills, and gives you one fix and one exercise — feedback you can act on today.
One critique is a snapshot. A habit is a skill.
