Do you really have to play this piece? I don't know if its your playing or the recording but phrasing, and touch is VERY harsh. it feels like hammering down the notes, and the constant slips/mishaps throughout the entire recording indicates that you're struggling. A lot. My suggestion would be to work on other stuff but if you're keen on working on this, I'd suggest a metronome and (slow) practice. I'm not a teacher or anything so I can't explain it properly, but you really have to figure out a way to fix your touch. It sounds way too harsh.
