Choo! I liked your video very much! I think it is as you say, the recording makes your LH louder than it really is actually, so I won't complain about that again haha
I'm not good at pointing exactly what the problem is, so I will let Birba do it. But I feel that the melodic part on you RH is playing some parts at a different tempo than what it's written on the paper.. it's like instead of playing "taaa-taaa-taaa" you are playing "taaa..ta-daa" you know.. It's the poly rhythm thing between the 2 hands again. You are making this mistake everytime on bars 43, than when it repeats on bar 51. My guess is that you are not comfortable enough with the trill on the first note.
Also, the first 2 opening bars, that is bar 41 and 42. I think you should put more passion into it, you are coming from a very energetic strong section, that is bars 37-40, played in ff, when you get to those bars I would play bar 41 stronger on the way up and then play more softly and piano bar 42, you can even play a little faster.
Overall it's good, you memorized the whole thing. But I feel it needs more passion, it's what they say about "color" you know, I feel little difference in your dynamics, it's like the entire thing is gray to me. You have to put more soul into that, notice the accents and the change in dynamics and make your RH sing more.
That's what I think, but Birba will surely give a better explanation for all this
Keep going Choo!
