Thought I'd kick off the feedback for this track...
The track is way better than the original islands track, so good work, team.
The shipwreck and vertical hairpins are fantastic additions.
I have two small suggestions. First, I think the track should have plenty of vegetation, especially in the first part. But of course I don't expect that to be there in this first revision of the track, but vegetation would be great after everything else is said and done.
Second, when entering the shipwreck on the right side (see picture), on my first run it was extremely confusing where to go. I had to drive around in a circle a couple times to figure it out. I don't know whether the solution is better signs, removing some obstacles, a laser fence, or sloping the track more aggressively, but it would be nice to streamline that somewhat. Also, if you miss that hard right turn you run into a giant steel beam that adds insult to injury, even though it does add to the aesthetic (see 2nd picture). Even the AI was stuck on it.
