This one is really nice. I like the perspective you have it in a lot. Heh, it kind of reminds me of Bahamut from FFX though. I think it's the shape of the wings as well as the circle (halo?) behind his head.
This looks fantastic, the detail is really really great (i'm a huge fan of excessive detail, it's always worth the effort). i love the pose, and the facial expression, it makes him look contemplative and even a little bit vicious and maybe even insecure. i hope that someone colours this well for you, i can't wait to see it if they do. the twisted wings and the backwards halo are really inventive. absolutely love this one, keep up the good work!
