Wow! These many shifts in style were unexpected! This was cool but also sometimes a bit unsatisfying. All the time when a nice part developed it was replaced by something completely different in expression and style. Also the genres are partly that different that it might be hard to find somebody who really likes all the parts. The tempo shifts also sometimes are a bit too rapid. All in all this appears more as something like a medley or a demorheel of what you are doing. All the parts for themself are very well produced. You write that this is a remix. I don´t know the original track so I can´t say much about this here. Details to the parts:
The beginning is really relaxed and chilled with some nearly celtic influences. I really like this part but I have the feeling that the tempo shift around 1 minute destroys that tranquil feeling and the increase of speed feels a bit "stumbling"... Except this the upbeat part around 1:20 is very nice and also the shift to the piano parts at 1:50 is quite flawless. Maybe the modulation around 1:300 was a bit too sudden. The change to the housy part at 2:00 comes a bit out of the blue. But maybe this is just a matter of taste since I don´t really like this housy stuff. Really nice part again starting at 2:40ish. Your piano is really nice in this track. I also like the bit "grotesque" part starting afterwards and again nice transition to that chilled atmosphere around 3:20 which also gives a reprise of the beginning. For the rest my impressions were very similar. I really liked the piano outro! You also have some really nice piano sound... All in all it is quite hard to rate this track since it feels more like a compilation than a single track but I´ll give it a 5 of 5 since all the parts themself are really nice. You should consider developing full tracks out of the single parts, although from what I read in your description it was your idea here to create an "episodic" track. Anyway: Good Job!
