as stated above, the picture is very small and faint.
also, to make the picture computer-able, you'll need to give the outlines some darkening, otherwise any attempt to colour it will be nice and difficult.
I will hold off my opinion until I can see the image clearly, but the character's attitude is quite evident in the pose- very nice
*EDIT*
One thing i will say, though, is about the placement of the waist point. upon a second look, i noticed that the point at which the jumper hits the trousers is quite low. i'd say keep the torso proportional to add realism - raise the waistline just a fraction =>
