Interesting stuff. I've never encountered anything like this before. The relaxed, introspective feel is pleasantly organic.
I thought the words sat better with the music in the first piece. Perhaps that's because they play more of a part and the (my?) ear gets used to them more easily, whereas in the second piece, I found the interjection of the voice to be slightly distracting. Which leads me on to the fact that your piano writing is very nice.
