Old Sketch New Color

So I was looking through an old sketchbook from high school for some fun doodles that would maybe look cool colored. Sure enough I found an old character design that I made in about 2003-05 sometime, a rat warrior. Put it in photoshop and worked on it. No change to the original line construction just colored in and slightly darkened. Did two versions. one full color and the other one I liked with just the plain color background.
