I'll definitely be participating.
I was actually writing out some ideas last night before I saw the challenge. I said a week or two back that I wanted to do a town with some rather, uh, fantastical buildings! I was writing a list of places that I'd like to include, but I think I'll need to cut back or there are going to be more public buildings than there are houses. My only slight concern is whether I can do it all in a month, but since I was going to make this my next project anyway, I might as well give it a go as part of the challenge and see how far I get.
I'm going to do a star fort,
heavily influenced by this, though I'm doing a top-down perspective (and I'll attempt to get my shadows right first time this month!) I want to make a real fantasy-esque city with buildings that would probably work well in Disney's Aladdin. Dirt has no place in my fantasy city!
I hope a bunch of you will take part again. If you're a bit nervous about your skill level (as I was/am), please just give it a try anyway, because it's a huge amount of fun.
