Hi,
your introduction needs mor expression and the presto con fuoco more fuoco . Also i think you could polish a few parts e.g. : just before the last repetition of the main theme your right and left hand are not well balanced, the melody needs more cantabile. But the foundation is surely good.
I started working on this piece several weeks ago and some parts are really giving me hell, like for example the octave runs. Anyway, though maybe overplayed, the ballade is a really beautiful piece.
