Good work on general track layout and dimensions, seems quite good in this department, up there with the best versions of Suzuka i've seen (pro or modders).
The track has a couple of huge bumps, which i never saw anywhere in modern Suzuka, that make a road cars jump... i didn't try the track on modern single seaters, but i can see this being game breaking if not addressed.
Obviously needs a lot of work on textures, tarmac, grass...
