I think the strongest thing here is how well the demons contrast with the rest of the picture. Overall, it's pretty blurry compared to them. I now wanted to say that you show a lot of shots of these guys' butts. I think the shading is done very well. I've learned so much about your art style recently. It looks like a really nice canvas.
I realize that a lot of great things are done by just playing around with Photoshop or whatever program you use. You are one of the most prolific artists I've seen here. I like how it's enveloped in darkness. You get some strong emotion there. That's one malicious face.
