Why the rush with only 40 min?
I really think there is something in there that is quite interesting. While it uses dissonance, I don’t thing its bad sounding or overly dissonant sounding. More that it really adds to the atmosphere and mysticism. But I also think that this song could use some more tinkering. For starters I would really like some additional sparkling noises to fill out the treble frequencies more. A reverse delay with some pitch shifting for the piano could be a nice touch here. Also the placement in the stereo field could be broader and spiced up with some additional sounds for the atmosphere to get enhanced even more.
Overall I really like this song. It somewhat reminds me a bit of some older RPGs, like in an ice cave or ice temple, but with a more modern twist.
