ooo good ol' MIDI... how i miss you... well done with the composition! i love the usage of guitars later to really accentuate the more intense and serious parts of the composition! :D
one thing, which i also struggle with, is overlapping melodies starting to compete for space — the beginning ostinato performed by the atmosphere synth is very prominent and can overshadow the occasional cameos of the crystal synth, especially since there's the harp/pizzicato also playing in the background. perhaps velocity adjustments or additional panning might help!
