Opinion after the update:

A visually fun track, though the ambient effects can make the visuals a bit cluttered at times, it's mostly not a big problem. There's a lot of nice visual flare here and some really cool sections. A few obstacles aren't too clear without knowing of them in advance, but there's really only one or two I'd consider an actual problem. For the most part this is a pretty good quality track with a nice, if rather bright, visual style.

The updated version is definitely an improvement, and fixed the biggest issues. So nice job!

Unsure if the box tunnel was changed to be more clear, of if it's just that I'm more familiar with it. So can't really complain there. It wasn't really all that bad either way.

New mines placement is more visually interesting and feels fair now.

Laser Windmills, I can't really tell if these were changed other than the first one getting an extra ramp to give more maneuvering room before passing under it. Either way, that alone helps quite a bit. they still feel a little hit or miss, but I feel the issue is mostly fixed.

The submerged track section is way better. The glowing guide-lines showing the edge of the water are a great addition. I'd say the arrows on the middle of the track are unnecessary. With the glow, I couldn't even tell what they were without slowing down to take a closer look at that part of the track. I don't feel like they really add anything, and even take away a bit of the contrast with the guide-lines at the sides of the track.

That section still has an issue with the second moving panel jump over the pink barrier. It's essentially a blind jump, and with the track location, requires either fancy aerial maneuvering, or to only jump over the left hand side of it. Something that's not always reasonable with the moving panel. I'd say the biggest problem there is the inability to see where the safe landing zone is before making the jump.

This is the only real problem with the track currently, so great job!

Updatet

A visually fun track, though the ambient effects can make the visuals a bit cluttered at times, it's mostly not a big problem. There's a lot going on here, and most of it's good. There are several points where the track feels unfair, or lacks clarity.

First problem point would be the box tunnel. The coloration and fully transparent track makes it very difficult to visually understand what exactly is going on until you've scouted it out and understand the obstacle in advance.

Second would be the mines after a jump through the laser-gates. You can't reasonably see the mines until you're flying towards them at close range and in mid-air. This obstacle doesn't feel fair as it gives almost no time to react to it visually. You essentially need to know the safe route by memory, or luck.

The Laser-Windmills make for cool props, but I feel detract from the playability of the course. They're positioned in areas where there's very minimal room for maneuvering around the actual lasers, and they're far enough out to be moving at high speed without much time on screen. Making getting hit by one feel frustrating and like you were simply passing by at the wrong time, rather than failing to avoid an obstacle.

The final issue is the partially submerged track. The ocean water is a death zone, and it lacks clarity where the safe driving surface is, and where the death is. Again, a visually cool section, but doesn't play very well.

Ultimately, I like this track, and with some touch ups it could be really good. It's still mostly enjoyable in it's current state.

Looks great! The obstacles are interesting to avoid. Some obstacles were a bit too much though. (Mostly the obstacles where the road dips into the water.)
