Sketches from margins of school notes

It's a mini compilation of doodles I've done alongside notes I've taken for classes in college. I felt it was a nice little thing to do as I am graduating in about a week. 

There's a big blank spot in one of the pages, so if you buy this anthology of doodles, I will doodle something for you! Please email me (ykc1cha at gmail) for your extra doodle of whatever you'd like.
