How long have you been practicing this piece for - as you said it's been a while
I think you're off to a very good start on the piece. Now, I would now aim toward getting more of a "blend" or a "sweep" in the arpeggios and especially in the cadenzas, so that you no longer focus on each individual note, but rather on the shape and direction of the phrases. A good example would be the velocissimo passage just before the Un poco pił mosso, which ends in one great sweep up the keyboard. (Don't be afraid to use a little pedal here; it's not a dry technical scale, but a great Romantic gesture.) And you can make a lot more of the dramatic pauses in the music, like the fermata in bar 21 or just before the key signature goes to four sharps.
I don't use pedal on my scales, because my teacher doesn't want me to play any scale with pedal. Sometimes I don't agree with it, but I accept it.
