The medieval fantasy I just started drafting? I have a VIVID image of what the cover looks like. I just have to make sure I can eventually convey that to the artist.
Gypsy Fiddle? I have general ideas, certainly more detailed than what I'd been able to come up with for Paradox. So I'm not really disappointed that I can't afford to pay an artist for this one. I'm not really failing to reach my ideal, as there was no ideal.
I'm going for a symbolic representation in this one. There's a persistent image in the book itself that I'm going to try and draw. I'll probably start randomly sketching at the D&D table today. Just practice and try out the idea until I get it right. :)
