Crysis Rendering. CnC

This is intended for a desktop and I have worked about 6 hours on it. (Removing snow is a bitch lol) First will be stock image second will be rendering. Just give me some CnC as I intend to use it for a desktop so it needs to be perfect. What I did to it is below.

STOCK


RENDER


Things Done
1. Rendered it
2. Removed snow
3. Color Enhancement
4. Head Replacement (was too light)

I need you to grade me on my work as well as tell me what to improve. Thanks!

Please tell me if you see any snow I forgot to take out... that stuff is a bitch.

*I uploaded image to my website and will re-upload as I make improvements as same name so after you leave feedback it will probably be fixed up top =)*

*12/10*
Some people on other forums were complaining about how dark it was, so here is a less darkened verson
*NOTE* this does not have as much rendering type edits either so there may be some mistakes not in the darker one.
