What sort of reference were you using (or thinking) for this? Cause I'm thinking Kelley Jones. I know that it's been a long time since you've posted this but c'mon, what does it take like 15 seconds to respond?
Really, I think this is one of the better Batman pieces I've seen on here, even if it is a speedpainting. What I like about this is that it isn't mimicking any other photos; it's dark, it's exaggerated, and it's surreal. Nice work.
