Well done! Very precise control - almost clinical. The ending could just possibly be a hair quicker, but that's really nit picking, and it may be an illusion caused by the rest of the run being so tight.
Hmm - will Kamirashi come back at you on this one? I'll just sit in my nice comfy (and slow) third spot and observe...
The ending is extremely tricky. It is easy to either miss the last red flag or die in the process. I felt like I was staying on the ledge too long, so I rotated left to try grabbing the finish faster. I got about 0.4 secs ahead on the outer right side and kept that lead all the way to the last red flag. I finished 0.2 secs faster, so yes, it can be done a bit faster (in theory).
The other difficult spot is on the outer right side... the tendency is to overshoot the slope to the 4th flag, which means you can't get lined up for the loop in the upper right.
