I love the way this feels as a track in most parts, and I'm not sure if this has been fixed in V0.7, but there is no dramatic bump coming into Turn 3 that just shouldn't be there. It has to be reduced or removed.
Also, I was lucky enough to be given a private tour of the track at low speeds a few years ago so got to see all the little details around the inside of the track.
I'm not sure how accurate you want to make it, but here is a great video that demonstrates some of the finer details of the kerb profiles and colouring.

I'm happy to have a private chat about the other track details if you really want to get the best character for the final product.
This is the vid where I took some info from

I tried to mimick the track based on 2010/11.
But yer still some work todo. Goto change some kerbs that I know are incorrect.
