Oooh, thats incredibly detailed. Awesome. How do you get that thin white line on the outside of the character?

Dude, you got some sick rendering skills. One point of critique that I'll give is that his left hand kind of blends in with the abdomen area a little bit, especially when zoomed out. Perhaps add a little bit of highlights to the hand or something to bring it more into the foreground. :)

So awesome. I love the angle and detail with how the pistol is held.
Also I'm guessing that's a male Spartan.
