Since this is a remix, I'll just focus on being nit-picky.
'Cause you already know that this is a great song and performance, right?

Anyway, here come some (inconsequential) nits:
At 0:10 it sounds like someone is turning down the faders. It's just a touch too abrupt.
Bringing instruments in and out is very effective - adding strings at 0:30, for example. Although the strings sound nice, they also sound like MIDI string pad. Pete Whitfield has a
nice tutorial on string writing that explains how you can add melodic interest to simple string pads.
The strings coming in and out felt abrupt to me, but I wouldn't put any weight on that.
The bass line at 2:35 is a nice walkdown, but it feels a bit off. With the prior syncopation, I'd have thought the bass player would have chosen eighth notes instead of quarters. (Or is that quavers instead of crotchets?)
Nice trill on the flute, by the way. And giving the flute the harmony is really effective.
Anyway, great job.
