The composition has the vibe of some of the good old exploration adventure/rpg game. Definitely I wouldn't be surprised having it in the game background.
I really liked the sound of bass and drone effects. I still would say that overall sound was a bit of dry for my taste, it could benefit from reverb/echoing that will make the overall texture more smooth. Also the sound level of beginning and the part with all instruments playing is a bit too different.
Overall, good job!
