It's wonderful!
There are so many positive things to say!
The piano is sublime from the beginning. The atmosphere is radiant and sunny. And bam! At 43 seconds, we have a harmonic progression coming from nowhere that fits perfectly (I'm studying it on the piano because I'm particularly fan of this funky little kind of the chords).
Then the melody starts again with a kind of electro legato portamento flute which sounds great (if you know the Katamari Damacy soundtrack, we are in the same spirit).
And at 1'20" you go back to your funky chords but you enrich them and you go even further in the progression! Splendid.
After that you made a beautiful part more minor that adds variety.
But I would like to emphasize your transition at 2'25" which seems to be minor and major augmented (?). I love it!
Well, compliments are nice, but criticism is a good way to progress.
So here are two points that in my opinion could improve the mix
1- the bass is probably too much on the left. It's usually more pleasant to listen to it in the center
2- the drums are too loud compared to the other instruments, especially the bass drum which takes too much space for my taste.
That's it, I've already said a lot. You are in my top 3 of this jam. Bravo !
From the quality of the piano composition, I think you are a pianist. Am I wrong?
