Why does my drawing look off?
Draw it here or photograph it off paper. You get one specific thing to fix and a short exercise that fixes it - measured from your actual marks, not guessed at.
What gets measured
Five things, all of them technique. Never your creativity, never your style - those aren't ours to score.
Line confidence
Smooth, committed strokes rather than hesitant, hairy repeats.
Proportion
Whether the parts agree with each other and with the reference.
Placement
Whether a mark lands where it was aimed.
Corners and joins
Whether corners meet and shapes close.
Value range
Whether there is a tonal range or everything sits at one weight.
How it works
Most of the measuring is plain geometry on your actual strokes - how much a line wobbles, whether corners meet, whether a mark landed where you aimed it. That is arithmetic, so it is instant, it is free, and it cannot make things up. There is no daily limit on it.
Anything geometry can't see gets a second look from a vision model, and a finding only reaches you if several independent passes agree on it. If we can't measure something on your submission - a phone photo can't tell us about pen pressure - we show you nothing for it rather than inventing a score.
You'll get one thing to work on, not five. Five criticisms at once is how people quit.
What this is not
We never draw anything for you, we never generate art, and your drawings never train any model. The point is that you get better, which cannot be outsourced.
