I really wanted to leave a review on this one for quite a while but I never found the time :( It´s amazing how you put so many different moods into the arrangement of a single pop song! I did some string quartett arrangements for pop songs a while ago but I definitely wasn´t this creative like you here.
When I heard this track at the beginning I think the master was a bit dull but I guess you remixed it a bit because I think it´s much better, now.
Okay here are some impressions I had during the different parts:
Beginning: Calm with a feeling of minimalism (especially in the strings)
Arround 1:30: More in a happy climax. Very cinematic (Still with a bit of minimalism)
Arround 2:40: Some chanson elements in the organ give this a bit a feeling like in a coffee in Paris.
Arround 3:00: Very dark, climax, horror, cinematic.
Arround 3:40: Clockwerk Orange!
Arround 4:10: Happy Ending climax with some SF elements.
Arround 5:00: Sad ambient ending.
I really have now idea which story would fit this track but it´s great. You did some amzing work with the chord substitutions here creating different atmospheres. The only thing is that maybe the melody could be a bit more present in some parts. Other than this: Great!
