Here are some concepts I had of the buildings that have been constructed in Winter Haven (http://www.winterhavenlarp.com).

The idea is that after a terrible cataclysm struck, all of the buildings were destroyed. The only lumber that has been found in quantities was that of ships that sank in the bay. So the people have drug up the ship planks (or pieces in some cases) and built their houses out of them.

This uses the same technique I used for the Portal... drawn in pencil, scanned and digitally colored to look like watercolor on old parchment.
The edges of this one didn't turn out as good as the portal, but.. *shrugs*
Again... still trying out the .PNG for the alpha-channel drop-shadow transparency.
