This one's my favorite, although probably not my best work, i just couldn't get the detail the actual helmet requires. This is A male Commander Shepard from Mass Effect 2/3 (i kind of mixed the armor to make it look good). he has the famous "Recon Hood" helmet. if you find a way to make the small detail lighting on the hood work, please let me know. otherwise, i think it's pretty good.

Enjoy!
