Hey there, I really like your model so far,
very nice hard edge work on the armor (? if i can call it like that
Obviously there is some work to do on the pants,
not quite sure what you were trying to do at the moment, you can't feel the cloth and or the fold, pretty messy. Maybe you should head in something a bit like in Gears of war 3? Did you see the art dump? go Check out the pants on one of the male character, I think something like that would look great!
