Perhaps you can get a contract with US Games which will enable you to release a small black and white print run (may via the Game Crafter, so you won't have to go through the hassle normally associated with self-publishing)? I do understand where you're coming from. It does feel good when one's work is picked up by a major publisher.
As I said above, your style reminds me a bit of the Tarot of the Origins' (
http://www.aeclectic.net/tarot/cards/tarot-of-the-origins/). It might give you an idea on how a colored version of your work would look like.
While I do prefer the nude version, I like the compromise you did with the clothed World card. The flow of the fabric makes it look like a natural part of the scene (as opposed to something added). I did notice, however, that the cloth's shaded areas appear more solid than the shading you did for the other parts of the image, which made it look a bit inconsistent with the rest of the image. Zoomed out, it looked like woodcuts, and I had to zoom in to see the hatching in it. So maybe you should add more hatching to the details you add to make it more consistent with the original image.
