I somehow didn't notice this thread until now, and I must say you did some real good work on your little western town! I imagine it would work well for a skirmish game set in a frontier mining post or at a crossroads... Or even at the outskirts of a larger town where the building desnity is sparse! Basically, all important buildings are there: A gunsmith from which to buy six-shooters, a saloon where to drink and pick fights, the Sheriff's office where the bad guys will get jailed, and the gallows where they end up getting hanged!

The ground and background also look great. The rocks make nice little cover pieces, and we all know how important cover is in gunfight games

The option to remove roofs is important as well, although with smaller buildings it might get fiddly moving figures around inside

You could try printing out business signs for your building fronts, probably easier than painting it by hand. I'm sure your town will keep on growing, so keep up the good work!
