Very nice, reminds me a little of calyx and teebee.
Only minor things I might say are that the drop seems a tad muddy, but I think that's just because I like tracks with a lot of space in them, and possibly the second half of the build could use some sort of riser/faller as a common thread throughout the whole section to build extra tension.
Probably nothing though, I just always try and say something to be improved.
