I think it looks spot on. I recognized it instantly when I saw it. In the origional artwork the drow has a brownish look to her. Looks like an effect from the light, but as to why a drow would be in a well lit area? I'm assuming it's drow, can't remember what module it was on http://www.larryelmore.com/ArtGallery/AGColor/AGColorFiles/TheOffering.html When I think of dark elves in a dnd sense I picture them jet black. Otherwise a dark elf could be whatever you wanted. As to them being light skinned from lack of sunlight that would make sense in a realistic way, but when you involve magic and myth all realism goes out the window. I'm currently playing in a drow campaign, and my friend the DM decided they are black because the were cursed whe nthe ywere forced underground. In his world sunlight is eventually deadly to them. So to each their own I say.
