One annoying thing was the rhythm didn't match during the descent. It felt missing. I guess if it were performed by a human, he might shape it so that it does feel so chunky.
I agree with the first part, it does degrade the overall impression of it being a completed work. Maybe firefinch could fix it?
As for the latter bit, I must say, although it may be just an inaccurate description, but I do believe it says "composed and performed by R.Goldfinch"? Perhaps it's just that firefinch played it and recorded it on a digital keyboard with a digital software that makes it sound computer-generated?
