Thoughts while listening:
Love the opening beat. The backward violin sound is a bit loud for the mix, kinda buries the piano.
Interesting change-up at 1:00. Some nice jazzy chord choices on the piano.
Thoughts after listening:
-The backward violin sound (might not be what you used, but what it sounds like to me) is too prominent in the mix. Almost drowns stuff out, and it goes on a bit too long in the intro...not on the first listen, but quite quickly, it would become grating, I feel.
-Would it be possible to adjust the piano up an octave? You've got everything in the same sound-space, so it's difficult to hear the melody.
Some Good Things;
-Great vibe going here!
-The piano solo is wonderful...would like to hear it a little more clearly!
-Awesome adjusments on the percussion. Great to hear someone giving it the attention it's due!
Overall, very original-sounding piece you've got here. Kinda what I'd expect out of an eccentric Anime, like Akira. I very much likes! Double-plus-good!
