Great painting skills you got there! And your colour scheme fits in perfectly. Also, the basing is very good!
As regards the cold one, I can't agree with asrodrig. I think it looks awesome! When I first saw the DE cold ones I though they were a bit too thin to bear a saurus but now that I see a saurus on it looks great!
If you don't mind, what colours did you use for the skin coz it does look very interesting as a colour scheme?
