I Drew On My Friend's Sketchbook

So I kinda blew up my art teacher's mind today. I was in her class, but instead of working on my assignment, I just couldn't resist sketching all over my best friend Lily's sketchbook she left lying around. It's got all these amazing drawings and spaces reserved for future projects, so yeah, definitely a risk. But the funny part is, she wasn’t even that upset, seemed to think it was kinda cool how detailed I got with one of her unfinished pieces. Still, my art teacher didn't take it well at all.
