Hi donjuan,
I want to commend you on having grasped the lively spirit of this opening, and on some very good fingerwork. The one thing that I would ask you to consider is, what is the rhetorical meaning of this opening? What concerns me at the moment is that I am not able to find a moment in your repetition during which to breathe! I understand your wish to make haste and the display the virtuoso technique that Liszt études do, but remember that Liszt's technique was one of the mind as much as of the fingers. I believe it would serve your development well in this piece to listen for yourself, asking yourself at every moment - did I understand the phrase? Is the punctuation clear? Am I tripping over my words?
It goes without saying that I am sure you have the technical command in your body of this prelude - what it needs now is a bit stronger of a musical intention to drive it.
Very best wishes,
Michael
