ice requires more than one color. also try increasing the constrast of the colors and making the hilights sharper to make it look more geometric. not bad though.
its pretty good but honestly most of it dosent look that icey , you could have just made the skin frozen (like put ice on it) and add some white to make it look more frozen and stuff. Needs some work 3/5
His scales doesn't look too much like anything. If they were ment to look like ice, they should have been .. well .. more shiny. I have to break my own "rule" and suggest using dodge on it. Not hard but a little. I think it will make it shine some more.
