Love the setting and the building. Reminds me more of Django! Would reccomend some more terrain work as against a ground plane. The road can be depicted by a terrain with wheel tracks, hoof prints etc going through them and Landscape in the back ground. But I guess you might already be working on them. The shadow doesn't seem to match the light set up. Its a bit to harsh for an over cast day feel which you have acheived for the rest of the image.
