As far as your armor guy goes, he looks like a mixed bag time wise. His head/hairstyle/texture looks very retro, 50’s 40’s. It looks very much like something from the dik van dyke show. (60’s) Most of his armor looks that way too, however the grey parts that are under the major pieces look very similar to Crysis, very future foward. If you want to change it I would go with downgrading the underlying material/texture to something a little more back then, perhaps a leather texture with the same shapes would do the trick, it could be a lightened grey leather, but at least lack the hexagon shapes within it. To update it all to now you would have to redo the hair, the texture on the face, and much of the armor texture, as well as a few key pieces in the armor. Namely the hole in the butt of the armor, it is a very strange piece to have a huge square hole right there. I realize a man’s gotta do his business somehow but I wouldn’t want to go about doing it this way 
Hope this isn’t too harsh, you said C&C Wanted so here is my 2 cents!
On your other model, the facial textures are looking great, the little grey object on the headdress seems to clash but I haven’t seen the reference you are working from, great job!
Thanks for posting your work!
