I saw this at Nathan's table at WonderCon the weekend before last. It's a very striking and eye catching piece. I think the shadows between her breasts got a little muddy/grayish, but that also might play well into the "sleeping death" she's in. Other than that, this is simply wonderful work! Awesome colors, David!
I don't want to jump to conclusions, but something tells me that this Snow White was asking for this...
Since it would be all too easy to comment on Snow White first, I'd really like to comment on the kind of sinister atmosphere you created with your colors. The cold-to-warm coloring of the floor makes it feel like the scene was part of an evil plot and makes it feel like there's something about to come in from a window. The shininess of the apple also manages to suggest an unavoidable allure towards it, even as a dangerous skull can be seen within it.
Regarding Snow White, even though the scene should probably be portrayed as a tragic one in a more traditional sense, the color scheme you worked with really helps in tilting the scale towards a more sensual vibe. Of course, she's also showing more skin in general, but the actual tones for the skin and the lips do a great job of pushing her attractiveness into the forefront. Less obvious, but also cool, is the look and texture of the actual corset, making it a more complex and elegant design.
