IronMan

[Untouch]

Some of the c4ds are badly placed and I really don't like the text nor it's placement.
You should make use of the dodge and burn tool will help your signature a lot.

I think it would be cool if everything but the iron man render was black and white.

Pretty nice looking, i enjoyed looking at it. Would be nice to see different colors with other comic characters such as spiderman with a red, white, black, and maybe blue scheme to it.
