Hmm... Can't say I like it a lot... There's the bright lighting on the left, and it looks like Master chief should be lighted from the left. However, that's not apparent in the sig. But imo, it really just shouldn't be the render, other things that are close to the light should be lighter. The effects seem a bit overdone, I think the sig needs some negative space. It seems like it needs a bit of depth too. The lighting looks blurred, which gives it the appearance that it's a beam of light behind the MC, but yet, some of it goes over the render. Some of the smudge right in the lower middle of the sig (below MC's face) doesn't seem in place. Keep workin on it. I like the idea, but I think it just needs some work.
