Speed up and more power, that's what you need to add. The rest is good imo, nice playing!Maybe watch this video by Boris Berezovsky playing Etude No. 10 in F minor: https://rapidshare.de/files/10182964/Berezovsky_-_Liszt_-_Transcendental_Etude_No_10__Appassionata.avi.htmlMaybe you see some nice fingering he uses, that you can use if you like to.
What fingering are you using?
