How is it in-game?
As I said to a couple of friend who I showed the project to, I'd probably have a lot more interest in the topic if I were posting textured shots from Blockland but it's not worth the effort to drum up a little interest and hype up the project.
For in game screenshots I'd have to retexture it from scratch every time I edited it, there's not any way to update the map file from inside sketchup.
I've tweaked the display settings to be a bit less drab while I'm working, I can make a quick rendering in it since I'm sure everyone would like a little color.
EDIT:

In case anybody cares, the shadows match those casted by the sun on a late August/early September evening.
EDIT2:
I wish I had know about this earlier:
