Honestly I think the lighting source is just a little bit to bright. Also IMO I think the top left is to much of a solid color. Maybe make it a little more cloudy? Another thing on the left of his body maybe you should add some of that pinkish color you have on his body coming out around him?
ya i agree with hazed the colors on the graphics dont seem to match the render, also the lighting is a bit to bright. its decent though
