And the winner is:

After a very scientific voting process, in which many votes were registered verbally, and after which we just decided what we like best anyway, the winner is elevation #3. We wanted some rock on the 2nd level to break up the siding, and Doug was right, the tower just seemed to cry out for it. We like the garage best with the rock over the door and the board & batten above that. This setup can mostly be done from the ground, and won't cost as much as some of the other options. Thanks to everyone who voted. If you got it right, give yourself a pat on the back.
