But it's lacking a bit of shape to me, primarily on her rib cage and neck if you ask me. It's need a slight curve to so she doesn't look like a board.
Also it missing some shading on the dog's (wolf's) head it looks flat compared to the rest of the body.
Also I'm not too crazy about the gradients on the text.
And the background is too dark around the bottom... I think I'd look better if the flame were in front of them and faded up.
Those are my thoughts but other than that I think it looks good.
