Very nice, expressive and beautiful playing, it fully does justice to this wonderful movement.
Before this rendition I would probably say that using so much tempo changes is just taking too much liberties, but you convince me it isn't. You bring the melody out very well, dynamical nuances are observed well, the rests are usually as long as they should be (though I noticed a few slight rhytmical perturbations, like a 1/16 too short, but this isn't much of a disruption anyway).
Just for information - why isn't the LH chord at 2:16 an octave lower? I know that would be not in the range of Beethoven's piano but it seems a very logical solution here.
