Very well played, such a difficult piece ! How long have you been practicing it ?
Personally, I think that the section in 4:40 is played with too much rubato...and from 7:30 onwards it seems like you''ll lose the train ( too fast )u.u And the end, from 8:32 to the end, it was...very strange, why did you do that sudden stacatto ? kinda cuts out the essence, the soul of that final section, which is the most tragic, and the stacatto seems to ruin it ( in my opinion, it's your interpretation

)
Anyways I enjoyed it a lot

Your technice is amazing. And what a fingers !!
