EDIT: It's done, and my cow doesn't look so demonic anymore.
We had to design a package for "cow chips" for class. This was done using vector art in Adobe Illustrator. Basically I traced the outline off a googled picture of a brown cow and messed with it until I made it anime-ish, added the text and stuff, and googled some cookie pictures and applied a clipping mask to them.
This makes me really want some chocolate milk or some pocky... =/
