Thanks for the story and the music.
I think I'd rather kill myself than killing and eating my dog or letting him kill me.
Life after eating my own half a pet half a friend dog would be unbearable.
Thats a... deep thing, I wonder how the author thought of that.
No wonder it gave you the urge to write a music piece.
I actually think that a bass flute could give you a good native sound.
Some parts at the first movement sounded much happier than expected, I wonder why.
The story you told sounds pianful and tragic, not cheerful and happy.
It might be just me.
Also, I think you could do a better use of the pianos low register, clusters on the lowest octaves can have a terrifing sound (that I really like btw),
Could be used to describe this hunger, the false hope, and the image of the horrible man-eating spider god.
Other than that... you gave me a good feel of these endless plains of ice.
You used the breaks wisely to give the feeling of emptiness.
Have you thought of performing that piece?
