I don't mind the color (the other Racial Altars' statue's are variously greyish, silver, dark bronze-ish, or gold-ish)... But it needs to definitely lose some definition. Especially (hopefully only) by replacing the texture with some kinda rocky, non-descript one...
To get what I mean, take a look at any of the other Racial Altars. You basically see a formless, faceless statue; maybe some eyes? Not much. This guy looks like you just stuck a gold-ish Proudmoore on top of the pedestal; he should look like a statue.
But I can't wait to see what else you got in mind. : )
