Thanks everyone for your inputs.
Chris, you are right about the too high reverb. For some reason, it sounded just fine when I recorded and then it appeared to be too much once the recording was done. I suppose it must be linked to some unequality between some inputs and what comes out at the end of the recording chain.

But I doubt I could do a new recording anytime soon (I wish I had more time for piano).
Whoops, forgot to change the usual Newton nickname before the upload. It's simply an artist name I often use for discretion, as the Internet is not always the most secure place. But it's OK if my page shows or if you guys prefer to change the file infos if you want when you place the file for good on the site. Just for the record, in french, ville = town and neuve = new, hence the choice for the Newto(w)n nick. English people can't pronounce my real name anyways.
Back on the piece, it's true the finale gave me a little headache rhythmically. I guess there's no easy piece with Sergei. Earlier, in the middle section, there are left hand passages that ask for such wide gap patterns (although effortless for him) that I had to practice them for a few minutes only once every hour or so, otherwise pain would show up. And as those passages are to be played legato, no choice but to stretch those fingers. Probably Sergei was a little bit masochist.
