That's sweet! The little buildings even appear to have shingles on them!
With the depth of field the way you have it, it even looks like a photo of miniatures. Tres cool.
Yep. With some colour, this would make for a very nice alternative map, I think.
See, for example, the temple map from the Fantaseum-Spring08. It's indoor and the shadows still comes from upper left corner (in this particular map I'd adjusted shadows to the light from the windows - but it still looks ok with the shadows).
Great map... I especially love the 3d one as it does look like a place to set up miniatures ... good job, I like it.
