I like how spooky it sounds in the first few seconds! Then it starts getting all mystical. I like the how the flute and, (what sounds like a clarinet?) go well with a call and return. The Bells all they way through really give it that ambient/calm feel. Kinda wished it just ended that way...but thats just because it reminds me of the mood in Minecraft. haha
Regardless Good track. No real issues in regards to mixing or arranging. Well Done!
