Yummy Slice of Frustration

Wasn't sure what to put this under, category wise. Anyway, something I drew in math class in this cool new mini-sketchbook my aunt got me! (yesssss) Anyway, I think it looks pretty messy. Some of the messiness was intended... and then other parts were like... oh. no. For example, a lot of the pen marks in the black were supposed to move in a certain flow, but it ended up not working that way, and I didn't want so many parts of the background peeking out in the black part. Even so, I like the texture it gave. But, that's what I get for using a pen I use for regular classes! lol I want to get some nice pens. Anyway, here's a slice of frustration. ^_^
