Drawings Next To More Drawings

I decided to do a little drawing exercise playing with negative space. Basically what I was trying to do was fill up a whole page with drawings whose outlines are outlines for other drawings and have no background or negative space. I didn't get very far before getting tired. So this is what I have so far. I think I'll work on it bit by bit, kind of like putting a puzzle together. Maybe take a look every once in a while and see what I can see and add a little here and there. I'll post more as I fill up the page.
