I just saw you post Mazeppa again... so sorry, please don't take me seriously, I am really an amateur with no music gift - I can't judge anything. I simply meant your Ballade 4 was incredible - every note was deliberate and from the heart! (And your Ravel was heavenly too) Having said that, I did notice you had split moment hesitations in Mazeppa here and there, which don't seem based on your interpretation, rather a split moment looking for notes.... But what do I know, I am really an amateur with no music training, mostly self-learned, can't play 1/100 of what you play. I am just sharing my impression, because you deserve the best! Good luck on your competition! Just one more thought, what does your teacher think? It's not useful to ask online, as you'd get comment from people like me who is completely unqualified.
