I'ma real sucker for realistic madness styles with lots of red, but I still think this is cool even objectively. I mean, agent seems a little rough around the edges (literally, hut considering what the piece is about, it's pretty fitting. I like how he seems old with the glasses. Old and tired. And I like that bat guy who seems young and ruthless. New generation of madness, I guess. The composition is really nice with the beam and everything. I really appreciate all the detail, like the little lightning around the beam, the graves and dead grunts, and the city in the background. The way the characters blend with the background a little bit, like their edges aren't super pronounced, is cool because it kinda shows how the madness swallows everything. The contrast in attitude is cool too, with the old agent looking at the beam, hoping for an end to everything, and the younger one seeming disinterested with the beam, carrying about his murdery business. I wish that one guy off to the right stood out a bit more and wasn't only partially visible, though, it's kind of annoying.
Overall, great job with the style and awesome concept and message. You really nailed the atmosphere. Just that one guy is why I'm taking off half a star.
