Hi Faisal,
Preparing this polonaise in two weeks is certainly an accomplishment, but the practice is not to be encouraged. Despite your excellent concept of the piece and your amazing talent, many times one can sense your insecurity, not so much about hitting the right notes but about just how to do it. Over the 50 or 60 hours that you practiced this piece your fingers have evidently learned it, but I don't think you have spent enough time thinking about what exactly you want to make of it. For example, do you really want to emphasize the bass ostinato in the trio to the point where at times you can barely hear the melody of the right hand? The other thing you may want to give more thought to is the consistency of the general tempo or pulse throughout the piece. There is a drive through this polonaise that must be kept up at all times, but on several occasions you seem to lose steam. All these are, I believe, mental issues. You have now practiced this piece long enough. It is probably time to give it a break, play it at most once or twice a day, VERY SLOWLY, and for the rest play it in your head, thinking about how you would like it to sound. BTW, you should know it well enough to be able to play it in your head from beginning to end, note for note.
In the meantime can we see some of the mazurkas?
