Quick concept - sci-fi helmet for a character

Not the best thing I ever made, had a bit of fun with the mixer brush though (in Photoshop).

On the helmet visor there should be a big R (hopefully it's visible enough), though I might redo it in order to make it even more obvious (duh). Maybe there's too much blue, kind of thinking of making the suit completely black, with hints of grey. I'm even thinking of a camo version.
