Actually, yes, I have seriously considered it ... Generally, if I were to do a drawing or painting, trying to make it as good as I can, it is nowhere near professional enough. For that reason I tend to do some pixel-art work like icons and walls, and design/effects stuff using photoshop, but using converted images by professional artists. But using a small child's artwork, I could create a fairly consistent feel that is not trying to be realistic. One challenge would be how to deal with combat icons to make them consistent as well. Anyway, I would need to work out what sort of module I think this would be suited to; not my ever-continuing epic, I think.
