Let me start off with, OMG I love the way you do hair and lighting. I really love the color choices for the hair and background as well as the texture of it. The shading on the skin is also beautiful. Very few things I think would improve this piece.
The woman's expression, she doesn't seem to have any whatsoever. Though possibly the character may not show expression, I feel that a subtle hint of some emotion would make her seem more fierce.
The only other thing I see, is possibly the brush strokes used as feathers in the wings. With the waves of vapor seeming to coming from them, I feel that maybe they are a little fiery and deserve a bit of golden glow as they taper out.
I really like the woman's blade and how it flows to emphasize her chest as well as add flow leading your eyes about the piece. Once again wonderful job, the characters are beautiful and well shaded.
Wow... Just...wow. I saw this in my inbox and I was excited to see that you have done another yet stunning and gorgeous picture! It always amazes me what you can come up with. But out of all of your artwork I have yet to see so far, this is probably your best. The colors of this piece is very striking and it could capture anybody's eye. All the small details are amazing as well. from a small seam to a simple small strain of hair, its amazing what you can see in this picture. The most stunning part about this piece to me is the hair and the sword that the girl is wielding. All those small details and all the special lighting is just amazing. The details in the man's sword is just as amazing as the rest of the picture. Seeing all the special lighting and all the itty bitty details on just one sword. The wings are a big part of the picture also, seeing that it takes up most of the empty space. The wings are very beautiful. Overall, this picture is stunning, amazing, and you can see how much effort you have put into this picture. This is a very awesome picture.
