You have really managed to capture the essence of Madness.
All characters are awesome, although the Auditor (shadow guy) seems to be missing something, perhaps a fist clenching in rage. Stan and Deimos aren't present but the main ones are. Hank is really baddass in this scene, and so is the Saviour. My favourite of course is Tricky, with [ERROR] written below.
The lines are smoothly drawn, with no jagged parts sticking out. There is depth perception, without removing the spotlight from the characters. I really enjoy the way you make shadows, it must have taken some time, or do you just draw them naturally like that?
