Oh, that is plenty awesome! Only change I'd ask would be you give it a slightly larger head and a little more shading on the wings (I sort of fell in love with how you did the Copper one, but Silver's still better), but that's totally an "if you ever feel like it" issue. Only two things that matter right now is I got my dragon, and that you absolutely rock!
EDIT: Oh, and if you could have him using his Ice Breath, that would be epic. Dunno if that's possible with size restrictions, as I don't know how much space you have to work with for that right wall. If not possible, don't worry about it.
EDIT 2: The more I look at it, the more majestic it is. Again, thank you, man.
