I have Piano in Blue, Keyscape, Spitfire Felt piano, the Braunschweig piano from Imperfect samples and a lot more and this piano still offers something else I think. In addition to the effects it also has a tone that none of the others have. Soft and dark, but still distinct and not muddy. Recommended!
Personally I don't think its too repetitive. I would alter the mix slightly though, like making the percussive, or basically every element other than the piano, louder and separate them more from each other. I think those elements in combination with the piano make the piece interesting, right now they are, at least to me, "hidden" behind the piano.
