arrowone, hit it. But instead fo cutting up a work, I would paint a smallish work, it would simply be a grassy plain, set this as the Panorama (I think, the one that if there is no tiles shows up as the background) and put a bunch of clear walking tiles on it. Then paint trees, bushes, buildings, roads etc. and then scan them, cut them out and load them in, a lot of editing would be needed to finish up the edges, maybe toss in some missing detail, etc.
Then you would be able to construct much more vivid landscapes, though the tileset would have to be very complex to be able to work.
