I really like your mix. It feels balanced. It definitely spoke of the 2 worlds! :)
Just a couple of nitpicking thing (but mind you, I'm still a beginner):
- I'm curious what it sounds like if you had put more reverb on it, so it sounds less dry
- The piano chords triatones, I wonder if you have played around with a more open chords (i.e. instead of F2-Am2-C3, try F2-C3-Am3, if that makes sense haha). My feeling about piano is that closed chords doesn't quite sound as nice as open chords on the lower piano registers.
Overall awesome job! You really did highlight the happier and sadder tunes very nicely!
