I found two laser cut bridges designed by my friend. They were waiting for a long time to be assambled. I have an idea to make another diorama to use those bridges. I have 30x40 cm plywood and two general ideas about this diorama. Concept 1 - Valley with the single line railway crossing it by the bridge. Railway line can be pararel to diorama edge or cross it at some angle: Concept 2 - Two double lines crossing each other: There might be three different types of landscape: A) mountain landscape B) Upper line crosing the lower one with earthwork approaches - rural area in autumn time C) Upper line with wall build approaches in city area maybe with some factory (KIBRI) What do you think ? Which concept looks to be the best ?
