nothing really too unique about it. It is also really bright and mostly white. Usually non-staged shots using effects dont work. I would say go back and try experimenting with a some effects and sseing what turns.
I really like the position of the head, and how the shields look over the Spartan's visor. Otherwise, I think that the shields elsewhere on the body stand out too much, and take away from the presentation.
I realize it might not have been staged but I can't say I really like it... It took me at least 10 seconds to realize what I was looking at in the first place. If the spartan's outline was a bit more prominent it could make the picture better but right now it's just a bunch of white and nothing else really going on. You can do better, cmon man.
