If memory serves me correct this is Chopin's final major composition. There are even elements of Bach in this masterpiece [implied fugato bs 9-19]. Ironically in my performance I kind of conquer the impossible musical difficulty of the 'a tempo guisto' bs 20-22 with my "paraphrase". The other "nasty is the seamless join at bs 91-92 which is marred by a page turn, but I think I convey the correct musical/rythmic balance to enable good phrasing of the triplet/semiquavor cross rythms. This lines up a nice 'agitato'. This is my mother's birthday pressent so I hope you like it.

I did research a large number of performances for reference and aside from the numerous number of "Liszt clones" corrupting this masterpiece and a rather unconvincing performance by Martha Argerich [by her God-like standards], Yulianna Avdeeva is one of the few that "gets" this work. Do a youtube search!

you should really invest in better recording equipment

if you can edit out that page turn, this will rank with the greatest recordings of this work.

It's obvious you must really love your mum. Perhaps for her next birthday you turn down the reverb. Lovely, really. Carry on.
