Very beautiful and detailed experience overall, acutally I forgot this was a mod, and thought it was official Kunos track. However one significant problem I can see when I enter the slow sequence of corners, the first two corners come too fast, they look like there is a distance to the corner, but when I drive there I am immediately in the curve without driving all the distance that I saw. Anyway I noticed pro drivers handle those well despite this problem. All in all looks very very good.
Very enjoyable mod but it can improve a few things. Many of the walls are a little high from the ground so you can see light under it. The AI is very slow in the twisty bits in the top of the mountain especially on the fast left and when the AI leaves you space to run alongside, they brush the wall a lot.
