I really like this. I especially like where you put the details and where you made things blurred and unfinished, with the face being detailed, the armor and "door" getting details but a little blurred, and the rest just being lightly defined. The pauldron and the bracer have great designs and the "door" is really interesting with the floaty jigsaw puzzle-like pieces.
Actually I really like the designs on the armor. Where did you get the ideas for those?
