I really like the point of view, and the way that white building is in the light. Would you consider moving the action up on to the roof of the white building, maybe making it a King Kong type thing, some kind of monster (about the same size, relatively, as the Bane figure) being shot at from a helicopter? I always like a big picture, with the action almost incidental :^) You need to be careful when you mess with the clouds, in case you change the lighting in ways you don't want to. You might be better off leaving the sky as is, but changing it in postwork. There's a very nice brooding feeling to it as it is, it's just not a very convincing texture. My 2 cents
