Crossing a bridge or 1/144 Tigers on the move

This is a small diorama for my 1/144 tanks. The idea was to try several different ways to build the bridge. Finally I decided to build a wooden frame and to fill it up with Gypsum. Once the Gypsum was hard, I opened the form and started to engrave the stone structure in the surface. Besides the fact, that it broke on the weakest position, I was very satisfied with the result.
