This is one of the "best westerns" I have seen in quite a while. The fact that you've built up the walls horizontally rather than vertically shows how much thought you have put in, and the look pays off too. You have made those blocky two-stud-deep prefab windows which I have never previously admired look much so much better with their new dimensions (as well as more useful - I've seen very few traditionally paned windows that are wider than they are tall). I also admire so many of smaller details including the frames for the prefab doors (again, huge improvement), the chimneys perfectly aligned to protrude, the black hinge plate for the transom/cornice above the window in the first photograph, and the fact that you've placed a group of basic bricks between the log bricks where a window ought to be so that it appears that a window was actually removed in the building's fictional past and "plastered up" as it would be by standard of the time.
As for the films, the only European Westerns I know are the gritty Spaghetti, though this premise seems ridiculous boarding on satirical - after all, this train must not have been the last to crash in Roswell?
