Wow this is a cool journey! Definitely a really 80's vibe from this, with really cool sound design texturing, and nice progressions and melodies. One thing to mention production wise, and very picky it is, is that around 1:10 to 1:30, there's a drum beat, but all of the drums except for a shaker/hihat are panned very right, and the shaker is more mid right. Also that synth is really left panned. Realistically, that melodic riffing synth should've floated over the top of the mix in a wider mid layer than the chord synths, and the kick and snare should've been mid mono and mid stereo respectively. The hihats could've stayed panned, but a better technique may have been a wide mid pan rather than a less stereo right pan.
Other than that this really suits a more modern interpretation of the brief! Really great!
