Sounds good
Well, the pianos sound pretty good here. And I like the "story" you are telling with them, it sounds very interesting.
I also like how both pianos have something to "say" in this track. Maybe the darker piano is a bit too loud for the other piano, but that's how life goes. The sad/cruel/evil stories are heard and the happy/cheerful stories are overlooked.
Only thing that bothers me is the long silence at the end. Is there no way to edit it out? Audacity is a good way to edit sound files, for example.
