Chopin Ballade No. 3 in A Major

[carcoleghoast]

I recorded this piece a couple of months ago, so I've improved some parts, esepcially the arrival of the coda where I do sweep-like motions. So, aside from that, what can I do to maximize my performance?

PS The audio is harsh because I transferred it to audio (for privacy), so please don't say that I sound harsh. Thank you!
