Sakura valley is probably my most complete track to date, although it leaves a lot to be desired in terms of the look and feel of the track, the track is based loosely on the smaller track at Tsukuba Circuit in terms of road layout, the elevations and surrounding area is all my own design, Originally the plan was just to build a track for screenshots, but as the project developed I added more details and worked on the track to make it a more enjoyable drive. The track features a main track area, and a visitors building/showroom for screenshots. It is still a work in progress so some areas haven't yet been optimised,
