I really like the realistic look and detailled texture on weapons !
So it will be some sort of Bioshock (FPS/RPG) ?
It have some Silent Hill touch with it's fog , good !

Yes change the hands, instead show nothing when unarmed, or give him aso a Commando Knife !
When walking the animation of hands and gun is bad, too much movement, hide them !!if you run you will run without looking at your hands !
Why not putting good hands and some commando gloves ?

Great work, keep it up !
