from top to bottom for those who don't know them: Spawn, Rip-claw and Ash.
three of my all time favorite characters, as a teen and college boy i marveled at Todd McFarlane's work (Spawn) and Marc Silvestry's (Cyberforce & riplcaw) and of course Joe Quesada's (ASH) learned alot from studying their stuff back in the 90's and still look ate those books and learn more. even now.
Edit: Ripclaw's leg (the one behind Ash) was a bit shorter than accepted, so i fixed it.
