Wow. That was fantastic!
The track was really nicely built, there were a few moments that didn't feel completely jerk-free, but it's quite hard to tell on flyers whether it's the track or just the odd viewing angle, so I won't hold you up on that too much.
The track shaping/elements were great! The twisted pretzel loop thing was pretty cool, and I really liked the flow of the rolls. The transitions between the 'flying' and 'lying' sections were nice, and there was a nice balance between the two. I'm a little bit biased towards the flying sections usually, they're usually a more fun experience, but it is good to have a balance and I think you had a good mix.
One of my favourite sections was the last few corners/hills before the final brake run actually. The small pops of airtime, the cool transitions, the rolling and twisting, it worked very well!
Overall, excellent. Another great one to add to your collection.
