Hiya! I spent some time doing a couple laps of the track to take a look at the fixes, and I have to say you did a really, really good job. There's still some problems, but once they're fixed I'll probably be raising my review to a full five stars.
The first, showcased in the first picture, is some weird geometry in this area of the track. The car falls through the ground and the area generally looks kind of glitchy and rough. Not well showcased from this angle, but take a look around the area in an editor or on your own. The area around the chicane seems to need some work.
The second is that these two treelines appear to still have some flickering going on! It's dramatically more minor than before, but still pretty noticeable as you come roaring downhill. It also looked like a couple spectators off to the left were popping in or flickering, so that area may be worth checking.
The third is that the track seems to have no anti-cut or out of bounds zones whatsoever. I can go off the track without consequence, and while the rough terrain makes it slower I would recommend considering adding these to the track.
The fourth problem is that the pitlane has two - one is that it doesn't count laps completed, and the other is that it has no speed limiter whatsoever - and if it weren't for the first problem, it would make an incredibly effective shortcut.
