Thank you for posting this. I love Smetana

This is very soulful music and it has to be played from the soul. At the moment it seems that you have learnt the notes very well, but they still keep you very busy, so you have not so much capacity left for living in the music. I suggest to work especially on dynamics, and especially on the p and pp! Since as it is now there is not yet so much difference. And a lot of the beauty of this music reveals through the p parts and subtlety!
One more thing: Those sextuplet runs might get clearer if you losen your wrist, I think. Well it's difficult to see on a video, but my impression is that your wrist is a bit too stiff.
