Too many materials, too many Oblivion faces, not enough actual texturing. My least favorite is the future guy with the blue discs on his chest. To me, there is no consistency, the materials don't make sense, and it just looks like you've tried and failed to make it look like GoW.
Don't just throw a texture onto the model, consider the edges, and decide what you want it to look like before throwing textures at it. Professionals would use base textures, like brushed metal, or fabric, then shade it to suit the model, but they start with a flat, uniform texture then add to it. Often, less detail looks much better, chest plates for instance on armour - they don't need blue lights, mesh, corrugated metal, and then they don't cover the whole chest. A plain, flat metal texture with a few dinks and scratches would look much better, much more believable. Without trying to offend you, I think you make it up as you go along, and that's a bad idea no matter what your skillset is. If you have a printer, print out a white render of your model then draw the detail on, plan it out, then stick to your concept drawing as much as you can. Any attempt to copy GoW will end up in work that looks like a copy of GoW - get your inspiration from a more tangible and realistic source. Look at Robocop's armour for instance, or the original Halo. Even Halo Reach is 'reaching' with the armour on the Spartans, extra shoulder pad where it would make no difference, that sort of thing - it makes no sense to add bits to make it look cool, because the coolest armour tends to be the simplest. Really, keep it simple, dents and scratches on tarnished metal - lots of darken and lighten work, lots of layers so you can make it subtle.
You are not above critisism, nobody is, if you post work here then it's fair game to critisize what is wrong with it. If you can't handle that, then your better off not posting work. If you ask me, your in a rut, you need to take a little break from the forums and work on something that'll give us critic's an impression of what you can do - the only thing that is guaranteed to impress here, is originality.
Health, Ammo, and bacon and eggs!
