i'm a n00b when it comes to story arcs, so i have a hard time imagining how two such level-headed characters could be motivated to fight... but this is a really elegant piece with great aciton and perspective. nice hard blacks, not overdone. i think the street-level should be a bit busier tho.
Actually, a friend of mine, when he saw this pic for the first time, referred to him as "Evil Batman"
I kinda dig that; I think a lot of writers (Frank Miller excluded) forget that, at his core, Batman is a psycho who dresses up in a black fetish suit and hurts criminals.
I'm curious on your metal drawing , do an iron man sketch or pic.......
I think bats TOO dark imo, but your shading is damn amazing! It's fun to play with. I think (if you ever have time) you should try to traditionally ink this, not digital (or other projects ya do)...i should take my own advise, but i'm lazy & don't got ink $$$ lol so there hehe.
