It's been a long time. Good to see you! Thank you very much for the thorough analysis. I agree with some of the things you say - like that I could come down at places with more bite. Believe me, I want to do that and really I try to do so, but I'm a weakling and have wrist problems so maybe it's not coming off as hard and loud as I think it is as I am sitting right there at the piano.
No one has ever mentioned the phrase issues at the beginning - the LH ostinato. Very interesting, I'm glad you said all that and I'll surely think about that next time I play the piece. Regarding tempo - perhaps my tempo changes are not to everyone's liking, but I actually do like them.
Thanks again. Hope we 'hear' more from you one of these days.
