Really good work, this has been one of my favourite tracks since I first drove in Grid many years ago, you have done a really nice version of it I like it much more than pcars version, excellent work.
I like being able to drive into the pits via that first entry as well always wanted to know what that part was like.
Only downside is could be a bit more optimised on the textures, 590 megs is a bit much, but great work no the less.
