I really like the combo of everything going on here :)
The main instrument that the song starts with and progresses throughout is both really cool, but also plays a very beautiful melody. The gated chords and arps really add to this kind of spacey mysterious feeling. And even though the song doesn't get much more harmony compared to the beginning part, it still sounds pretty interesting and varied as the melody just keeps evolving in a very subtle but definitely noticeable way. It has a great mood to it in general, and can also easily fit some action-y game or scene. Just awesome job in general, keep it coming!!
