Your doing really good.. thanks for the color change.. he's really looking good..

I only see to small things that I would chang. Its really such a good job its nice really have to look to find things !

1) there seems to be a litle bumpyness on the outside of the horns. would smoth it a little as it just makes him look odveusly CG..

2) your elbo is higher up in this render than your concept drawing, and I really liked the perportions on the concept.

looking really good though.
good luck on the textureing.
