Thank you for the kind words, guys. Scenery has definitely become one of my favorite parts of layout building lately. I've worked on a variety of layouts this past year, and practice is definitely the key to coming up with something believable. 
Joe, I have a website (link is at the bottom of this post) but I haven't been very good at keeping it up-to-date. Part of the problem is that it was put together so long ago I've forgotten how I did it! I'm not really a computer person. There are also the magazine articles and a variety of posts on the forum.
The water wheel was built using thin modeler's plywood. The basic shape was cut on a scroll saw. Bracing was added with stripwood; the axle is a section of 2-56 threaded rod. I hope to motorize it someday.
