Hi!
Good interpretation of some stunning lyrics.
I think your intro, with the harmonics and the lovely piano, is really, really gorgeous, and i think it captures something of the essence of the lyrics.
I felt that the sort of unstable timing detracted a little...it's a bit jerky and the pauses interrupted the flow a little, where i really felt it needed to be a bit more closely coordinated and to keep moving. The synth sound that holds out single notes on those pauses didn't really do justice to the rest of the lovely sounds that you're creating.... But I think the musical concept really complements the lyrics and if you got the timing a bit more "flowy" i think (my opinion) that would help - and this would be really lovely.... I also felt there might be one or two too many clashing notes, and just as a matter of personal taste i think it would sound better with a few clashes taken out. On the other hand, i guess looking at the northern lights must have a kind of otherworldly feeling, which you captured well.
I hope that doesn't sound critical! it's not meant to as i think there's some really really beautiful stuff there, i just feel the beauty of it would be a bit more accessible and shine brighter if the timing were a bit simpler.
Nice work!
