Bullies Sketch

This is a gift for a good friend of mine, i have shown her the sketch and she likes it, i am glad ^^

You probably recognized them, those are character from Naruto; Neji, Tenten and Rock Lee. I wanted to draw them without reference and i think it came up pretty good.
I didn't want to draw them in their usual universe, as ninjas and all so i made them their school's bullies. I know Lee looks like a kind guy in the picture but don't get fooled by his kind looks or you might end up in a trash somewhere around the school grounds x) and Tenten look like such a betch xD

I will put colors later, first i would like to get something better than Crayolas to do so... if you have any idea of what i could buy for my drawings to look better in color, don't hesitate to tell me !!!
