This is one of my absolute favorites! I love how you transition from your main theme to that little aside at :25 by removing the percussion entirely and letting the xylophone take over completely. I also really appreciate that you add that higher pitched counter melody/harmony in the xylophone when you restate your main theme at :35 to add a new element to that section, instead of just repeating the first section again with no new material. Those types of little details are what keep a looping video game track sounding fresh after listening to it repeat over and over again.
There's a real clarity to your arrangement and overall mix that feels very professionally done. The orchestration is nice and sparse, and the music feels like it has room to breathe and isn't too cluttered. Also, that pan flute sound is great! What plugin did you use for that?
Overall, I absolutely love this piece. Excellent work!
