It's not a religious problem, per se. More of a focus problem.
The way I do these is a bit more like summoning than drawing.
I don't usually decide what or how to draw the avatar before I get going--I start with swirly fog and stare into it until I see the outline of something--something that suggests a shape that is already there--and then I just bring it out. It's much eaiser than drawing--like seeing cloud shapes. Almost anyone can see shapes in clouds. Photoshop lets me nail them down and show them to other people.
Usually this works pretty well, as long as I'm either willing to just take whatever comes, or have a clear sense of what I'm looking for. And the really best ones, they always feel like I didn't have anything to do with drawing them at all--they just come all by themselves.
Anyway, so. I've gotten enough weird results working on yours that I think I'm not focusing properly. Your avatar is being tricky and elusive, and isn't going to sit still to have it's portrait drawn until I understand it a level better.
Your spec was clear, and perfectly reasonable--should be well suited to my style. There's no problem there. But thers's something else missing--the thing that makes your fiend different from anyone else's. What kind of a fiend are you?
Tell me more about being a Duke of Hell, and how you got there.
