thanx for the comments.
with the directionnal light, it should create that little round in the eye but it doesnt, i dont know why maybe the light is too high.for the color i will try to change it.

now, the teeth are not textured yet but will be as soon as i can.and jhubbard, you said that they seems to glow and i think thats because the diffuse is way too high.

i hope with the fur it will looks better
