First try.. Ok, not first, but first serious try and first map that actually came out any good.
I used a lot of brushes found around here as well as some resources such as the folded paper, so it's not as much 'mine' as I would like. But I don't have a drawing pad, or any kind of drawing skills to compliment it so it's as good as I can get it.
The floating cities are powered magically from water, either a river, a lake or the sea.

But I'm a bit curious about how you all manage large maps. This is a fairly small map I'd say, with not much detail, but Photoshop lags like crazy when I open it. I have the Creative Suite Web edition, 64x and 4 gb ram. How are you able to work smoothly?

(It's smaller than several maps I've seen here, but still I can't upload it.. Why? Lossy compression?)
