I shouldn't probably bump this, but I thought I'd share give my input. I could see it being extremely good, but you cheated the background too much. It's clear that you used a couple of renders, I.E. GOG soldier and that UT3 character for the background and, honestly, it's not enough. Especially if you can see a face in the background, it breaks the illusion. You should mix things up a little by bringing other sorts of materials for it (Detailed c4d's that would go with the theme/aesthetic of the tag) or at least patch tooling to hide the fact that they're just renders. It's surprisingly good right now, it looks really nice, but just half-assed(don't take the wrong way). Hope that helped.
