Love the falling melody. Starting at 1:33 Is intriguing to me. To be honest, there were a couple of notes that sounds like "fumbling" on the keys, but I don't take them to be as such that would inhibit my enjoyment of the piece.
The unrest amidst the beauty of the beginning and end gives it a nice contrast. The hesitation between notes fits well with the discords throughout. You do seem to convey a story in your improvisations to which I can walk alongside with in my thoughts.
