Look at the thing you made from across the room. Distance shows what close-up hides.

Up close you see the parts you worked on; from a distance you see the thing itself. Those are different pictures, and the second one is what everyone else gets. Proportion, balance, whether the eye lands where you wanted: none of that is visible at arm’s length, because you are too busy admiring or hating the details you remember making. Distance strips out your memory of the work.

Pin your drawing on a wall and back up ten feet. Shrink your design to thumbnail size, or play your mix from another room. Then fix only what still bothers you from there, and leave the rest alone.
