Personally, dont like it, I think its a horrible concept to think about and do not like the gore of a fictional character who fights to help those who cant protect themselves. The artwork is great. Well done on the detail and the nice touches, but to see one sit and have a cig, after killing someone murderously who tries to aid others I find sick. BUT your art is very awesome, so please do not feel offended.
It's OK But Deadshot is a killer. He is maniac and people's life is nothing for him. He fights against Batman and he hates him. What he should do? Bring him flowers? "Bat is DEAD" series about villains of DC Bat Universe.
I'm not usually into, y'know, pointless character butchery, since it's rarely imaginative, but I really love these as villain portraits - their methods, body language, attitudes, and all. Like all good portraits, these make us think: "Yes, that's it exactly. That IS how it would be."
Hmm. If you're looking for more ideas, have you considered any heroes's canonical AU or mind-controlled selves as the villains? (I'm overloaded with text formatting today and my memory's a little shot, so please forgive if you've already done this.)
