It's the perfect combo of pretty and spooky! :D I can feel the apprehension in this piece! I like the instruments and the simplicity to it. I must say, however- fade-out endings aren't really the most creative ways of ending pieces. Maybe you could loop it. I would also suggest adding a little more dynamic/emotional contrast, but if it's for a game, I can understand your reasoning behind keeping it mellow throughout. I love the mood and the instruments, though. Great job! :D
