I couldn't even tell what these were supposed to be silhouettes of. I vaguely think the one on the bottom is Hank. It just that he has red eyes and it looks a lot like his head is covered in bandages. The viking on the left upper hand side looks like the guy that appears on the logo for gamezhero. At least I think it's gamezhero. I don't know what's in the background.
It looks like it might be buildings and I don't like to be reminded of the WTC. Seriously, I'm not offended by that kind of stuff and no one else should. I really like how you use a lot of good contrasting colors for this. It's just great atmosphere. The only guy I have no idea about is that guy on the upper right hand corner.
