That movie was freaking AWESOME! And I loved how it wasn't like invincible Superman, he actually got beat up pretty bad. That was really cool how he really had to try to beat Zod's guys. Also that one scene with Clark in the bar with that one guy was hilarious, he tried to shove him and he flew back a little, priceless.
I've yet to see the film but I really like Zod's re-design. I can't help but wonder if the U is a nod towards Ultraman, whom is the "Crime Syndicate" version of Superman , (in the Crime Syndicate universe all heroes are villains and all villains are heroes, i.e. you have a villainous Superman and Batman going up against a heroic Lex Luthor and Joker).
Anyway, fan theory aside I think you've done a great job on the faces and backgrounds on his piece. Nice work
XD I thought that was actually sweet how he cared so much for Martha and fights back (then of course there's the crashing through buildings and the menace in his voice when he shouts at Zod) That's what you get for going after Supes' mommy ^_^ Great work!
