Characters for Comp class

I wished I had done more with the colour, but then I didn't have much time to work on it...
in fact, I was only given a week, and you've gotta understand I have 5 other classes besides comp class..
that being said, I did still spent over 30 hours on this...making vector image is just so much work...especially the lineart, drives me crazy..
