Hey I didnt know I had a comment on this one... anyways, I agree on the fluidity part (working on the shading...) as well as additional highlights. As for the eye, I think it is just the picture that makes it look like the pupil is screwed up... thanks for pointing that out.
Taking a close look is not that bad. Need to keep the color more fluid, and add a few more highlights. As for the low points well look at what he did with the eye.....!
