It has been a long time since I've seen a 2D background so professionally blended into the 3D foreground! I take it this is a photographic background? Don't tell me you painted it yourself?! If you did, gawd . . . am I jealous!
Rest assured....it's a photograph of the Kamloops Lake area in British Columbia, Canada. I tweaked the colours and blurred the image a bit in Photoshop to match the foreground. I'll post the original without background later this weekend.

Hi Roundhouse: the background was added in Photoshop, a virtual landscape. See:

7 years later and having seen a couple hundred model railroads, some of the perfect, this is as good a sceen, more realistic than anything I have ever seen.
