Love the instrument choices. The vox are maybe(?) a bit too compressed and/or phase-y, unless that's the goal. The drums get a little lost for my taste. The ending caught me off guard. ?
Overall it's a good song.
I have not, cuz I ain't a score keeping kind of guy, but I watched the groove3 video about it and it looks pretty slick.
Also, I've not used CbB's staff view either, so I can't really compare.
