This is coming from someone with no drawing ability at all so first I want to say congradulations to the artist for getting his work into a D&D product. My own personal ability can't even come close.
I really like the coloring. I like how the hair has a tint of orange and how that highlights the cloak, the jewel and the red belt-like piece she's wearing. I like the raggedness of the edge of her cloak and I like most of the shadowing.
But there is something wrong with the arms (too thin and it's hard to see her left hand in the shadow so the hammer(?) she is holding makes her arm look strange) and she has an incredably vacant expression on her face. If she was miling or at least looked confident in herself that would raise the "hotness" factor quite a bit. It looks like that cloak has gone through some wear-and-tear but I have no idea how someone with her apparent intelligence and meekness could have gone through what that cloak has gone through. I also think her sword weighs as much as she does (so how do her arms hold that thing up?).
Not a bad start at all. A few good things there but she doesn't reach "hot" for me.
