Chopin and improvisations between me and my brother

I am listening, regarding Chopin's waltz: regardless of the inaccuracies and "indecisions," perhaps you are playing while trying to read the sheet music instead of playing from memory; besides the fact that I perceive a certain "rush" in your playing, which in some cases results in an imprecise use of the sustain pedal and obviously some passages. I have also noticed some passages that do not "correspond" to what is written on the score; I am referring to the arpeggio in measures 8/28 and the subsequent same C-G-E natural chord, which seems—though it's possible that listening via phone makes it less clear—to extend beyond the duration of a quarter note.

There is also an "extra" quarter note in measures 40 and 92; there, it seems as if you sense a "void" and prolong the duration for an additional beat. Keep in mind that this happens in both cases; it could be (it's just my impression) that you arrive at that point "as if you had run out of breath," so you need to recharge yourself to avoid losing your place, which is why you repeat the measure and then resume the piece.

I am not counting the errors because they can happen, just as the recording does not provide proper audio quality, in addition to the fact that there are points where the video is not fluid.

To me, who am not a pianist, it brings to mind when I used to play this piece: much rush and exuberance, but lacking cleanliness and pedal control; however, the instinct is there and can obviously be improved.

Another thing I noticed is that you tend to lift your wrists at certain moments; I imagine this is not correct or advisable as a movement because you lose strength and balance in your touch, and you tend to strain certain muscles and tendons in your forearms, which on the contrary should be as relaxed as possible. Am I right?

Well yes, in effect, yes... anyway, are you referring to Op. 64 No. 2?

Yes, at 70 no. 2.

I am the boy who studied Chopin's Op. 64 No. 2, the other is my brother

Ok, sorry, I had seen the first video.

I've just watched the second one but I need to listen again; the audio is what it is and listening to it on the phone is even worse.

At first glance, it seemed to me that it was played a bit too fast in some parts; for me, they would stand out more if approached slightly slower, then surely it was just the emotion.
