Having been on the real track lots of time (with my car and also rentals), I did get lost on this virtual one... So, here is what I noticed being wrong, compared to real life:
- track is too narrow and seems too short too
- no reference points, needs some buildings (pit), the poles with the start lights is missing (2:33 in my video), the pit exit fence's ending is reference point for braking for the first right hander (at 2:39, where the guy in red stands), it is missing the bridge on the top of the hill too (at 2:56)
- the fence on the side is all the same, IRL it stops at places, there are tires at places, making it easier to recognise where you are
- the surroundings are not flat, there are hills blocking vision at places, other places you can see far away (like at 3:17)
- some corners are too tight (3:54 felt too tight in game)
- curbs are too high (in corners) everywhere
- there are curbs on the right side at 4:07
It does look as a good starting point, though, if you need any info I can help (I live ~20 km from it). I have a half decent video of me driving on it:

There are probably many other better quality popping up on YouTube nowadays.
I hope you'll continue with it, it is quite a nice to drive track, with its elevation changes and technical corners.
