Those Exo-Force pieces. <3Anywho, my complaints:- Silver looks a bit out of place, but seeing as you had little choice in the matter, I give it a pass.- The brown/tan also looks a bit out of place, it doesn't appear as much as it should. Still, few choices on the pieces in that color, so I forgive that.- Arms/hands look kinda wimpy compared to the rest of the body, especially the hands. Could use fingers/fist piece.- blue pins boo (don't take this seriously, it's fine)Otherwise, I like the MOC! He looks pretty sturdy, like he'd take a bazooka to the face and feel nothing. He could use a tiny bit more width, but he looks great nonetheless.And the fact that he can cross his arms makes him all the better in my eyes.
