Well done for 0.1. The track has a great layout, short and easy to remember but very technical. Glad to have bumped into this one! The road bumps out of the pits and that same part of s/f straight might be a bit too rough, but it's not so horrible even in powerful cars.
I don't know if I understood your plans correctly, and if it is now realistic or not, but if you do plan on smoothing it out and with different modern curbs or something like that, please include this version as a separate layout, like an 'older and rougher' version of the track. ;)
