Great work! Now we just got to get you playing all those instruments. ;D
So nice to just sit back and let a track wash over oneself. Don't be afraid to let things groove when they want to groove, to shape the work along ups and downs as it breathes. I feel highs and lows in pitch, but I feel like there could be more sense of dynamic and rhythmic contrast. Sometimes I start creating a piece and I think one part will be the climax, and it turns out it is actually a different part that really is the climax.
Never stop exploring, dude!
