it looks very very good, but i have to points: the road mesh is ok but it could feel a bit more detailed and maybe a bit more bumps was awesome
second, the ai seems to struggle a lot with the fast chicanes and the pitlane. i raced with the 90s dtm and i could go flat out through the two chicanes on the backstraight but the ai breaked and shifted two gears down and some seemed to struggle to get out of the pitlane. if you could work on these things and improofe them it would be one of my favourite tracks :D
