Taste the Rainbow [lineart]

I had to decorate the front cover of my dummy for art class at school and it's supposed to represent your character or something like that. I didn't want to cut and paste pictures from magazines on it because everyone else was doing that already. So I decided to draw something :) In the end; it turned out like this xD

At the moment I'm still coloring this piece and I think my hand is dying x_x *cramps*

wheeeee~ 8D
