Ariel,
Bravo! This is the most powerful and sophisticated playing I have heard from you so far.
Good understanding of rubato and nuance, coupled with some pretty fabulous execution.
My only criticism, and this is quite subjective and personal, is of the ending. In bar 250, I think we need even more tone to convey 'ff'.
I don't like the rit. in bar 252 and bar 253. There is no rit. in my score!
From bar 254 to the end it sounds to me like you haven't quite developed enough momentum yet, and the musical feeling of the ending felt a bit stilted. Do you really wish for bar 254 to be in a completely slower tempo than bars 242-248 (which I thought you played excellently!)?
Anyway, congratulations on a wonderful performance of an exceedingly difficult piece of music!
