Sketch Diary: an eye, a figure, and a floating head
I once had an illustration teacher that loathed floating heads. I quickly got into the practice of adding shoulders in some way so it was more of a bust, way more classy. I always got good marks from him for my sketch homework after that. My real issue... is floating eyes. Singular, actually. As you can see here.
AHH! That hand. Don't look! Just keep staring at that eye. Or the pointy bit at the end of that dude's nose... that's my favorite.
