It's simple. It looks good n' clean, but it's too simple imo. Could use some more effects I think. I don't like text in corners either. The blending on Chief is pretty tight though. Needs some more foreground stuff to give it more depth. Overall pretty nice. I'm sure Onfire will like it a lot.
Sides need to be darker to bring focus to the Master Chief IMO. Right now the white regions are kinda overpowering. Blending on the Master Chief could have a smoother transition too.
