Hi David,
Thank you for such dedication to Russian composers! I think you capture the sprit of this music very nicely, with very delicate touch and feeling. If I could take a liberty and give you a critique, my suggestion would be--avoid downbeats--this is essential for MOST of Russian music and LOTS of Chopin (as well as Bach, BTW). Moreover, Schumann, for example, very often even with his writing suggested breaking bar lines (look for example, into Toccata, many Novelletten, Fantastucks, Sonatas, Fantasy, etc.).
As it is, with all the heart felt interpretation, it feels squared because you always go to a downbeat. Instead, start the phrase "from the source"--then pass and round the phrase right at the bar line--that's essential for most of the Russian music interpretation.
Hope that's of help.
Best, M
