I'm glad you provided a reference! I was about to start talking out of my

--- well, from looking at the reference, I'm better able to say what I wanted to about the piece.
LOVE the idea! Really cool artistic intentions behind it. I think you need to try to 'glue' the loose cloak to him more...what I mean by that it, if you start at the right shoulder, it kind of looks as if his body is oddly proportioned, like it's wider than it should be. Look at the reference you posted-- in my eyes, it seems like, while it is hanging off of it, it's still drawn to his torso pretty closely. I think it would help with design and give it more form. As far as the face and the hair, I think you spent a lot of time on the body and not as much on the face because you didn't know exactly how to tackle it. What I recall learning a few years back in in face details, little pixels go a longgggg way. So, maybe try to not emphasize the face details so much, put a few dots here and their to extenuate certain facial details but let the lack of abundant pixels define the face in it's own way. Hope that is helpful! Great piece!!!
