Here's a video primer I did on forced perspective

It used to reside in MRH Theater; however, when the hosting changed the link broke.

And on my current railroad

Here's a pictures of my mountain on my HO scale layout that has an N scale structure and vehicle 24" away from the viewer.  There's also an N scale water tower peaking out of the trees at the top of the mountain.

I used Z scale for forced perspective.

Thanks guys. I like the look

Thanks guys. I like the look of what you've done and i'm going to do roughly the same. Maxiumum width for the layout? 20" 24" Thanks.

I also want to do a trestle bridge on the hillside as well. Sort of like an abandoned spur. A small waterfall underneath would be nice too. Any pics of a layout like this anywhere, or a track plan?

excellent

Rick, you did and excellent job on your forced perspective. Not just the building and tower, but the trees and rest of the scenery just give it an even flow. 

Thank you, Dave S.

I appreciate your kind words.
