I would buy thepunishers if it was a cover or promo art. Green Lantern's head is a little wonky, but otherwise well put-together. I wouldn't have known that was Supes getting beat up by Darkseid if I hadn't read it the other thread, and you got tangents going on with Martian Manhunters nose and DS's kneepads.
Justice's is technically well-done, but just lacks something. The character's all look like they are striking a pose for different actions, and then collaged in together. That Superman is BEAUTIFULLY rendered, but the anatomy is way way way off. Very twisted in the mid-section to chest area.
My vote's for thepunisher; both are well done, and I wish this challenge hadn't been such a screw-up since day one. Good work guys.
