a good start, armor seems a bit big...in pulling this off correctly i think porportion is the way go....
i see these big guys and think to my self???? why not make the armor to fit them rather than a big guy in a little suit type scenario!
it should hug your body! you notice what we see, the suit and flak is a bit baggy. etc...
porportion is the key to any good suit...screen accurate or not!!!!!!!!!!!!!!!!!!
overall a good start
