Very beautiful playing! I like to listen to it. As far as I can say your emphasis seems to be on exactness and distinctness. Your pearly nonlegato style is very good. Keep that. Especially for Norton and Joplin its the ideal approach. In Beethoven i would suggest to work a little bit more on legato where it is required, on phrasing and dynamic contrasts. Sometimes your playing gets a bit monotonous, like in the first part of the Albeniz. This endless repeated motif in the treble i wouldn't play always at the same dynamic level, even if there is no dynamic written by the composer. What piano do you play on? To me it sounds like a digital, but in this case I'm not sure. And what sort of performance exam do you play for? Anyway good luck for Saturday!
The piano that I used for the recordings was my piano teacher's lovely Schimmel (grand). I don't know the exact model, but it sounds brillant when heard live!
