Proportion Practice

When somebody says a drawing looks off but cannot say why, it is usually proportion - the parts disagreeing about how big the thing is. This is the single most common reason a drawing fails, and it is also the most fixable, because it is measurement rather than anything innate.

The method is comparison. You do not judge how long a line should be in the abstract; you judge it against a line you have already drawn and trust. Half of that. Twice that. The same as the gap beside it. Working that way, errors stay local instead of compounding across the whole drawing.

These drills make you commit to a judgment and then check it immediately, which is the feedback loop that actually moves this skill. Guessing without checking builds nothing.
