Good lord, indeed! My dear, when you polish that Polish piece (say that ten times fast) it will be really, REALLY good! Have you continued this piece? We'd love to see how you have progressed.
Here's my critique.
Technically, very good, almost no missed notes. I bet you use the metronome. Am I right?
Musically, not so good, but dont panic. What I heard was a lack of shaping. The bass needs to be more lyrical and the top notes need to be emphasized.
Try this: starting at the beginning, play only the bass line while singing it. Be as expressive as possible. Play the bass as though it is more important than the treble. Try to create a sense of narrative with the left hand, as though you are telling a story. Listen to Murray Perhaia's recording, he does exactly what I'm suggesting to you. If you listen to his recording, you'll understand immediately how to do it.
I also wanted to hear the top notes more distinctly. To get the proper effect, try this. First, emphasize the bass note (forte), then very carefully play the right hand in this way: Play the bottom of the arpeggio pp. As you go up the keyboard, very gradually increase the volume from pp to p to mf to f,
with the peak at the very top. There should be a sforzando at the topmost note. As you come down, gradually grow softer to pp, until you reach the bottom. There must be a perfectly smooth gradation between pp to ff. You've got the technique, now concentrate on the sound. Proper shading is what seperates the amateurs from the pros. I think you've got what it takes to be a pro. You just need time to develop artistically.
So, play the bass musically (as though a divine chorus was singing it) emphasized but not harsh. Play the arpeggios with a shape that leads toward the peak which is the top note, and seamlessly back down.
P.S. You will have to slow down a little to make sure you cresc. and decresc. evenly, but dont play artificially slow or else you'll develop a note-wise performance.
Another suggestion; to get the sense of balance between the bass and treble, try condensing the right hand into a two-octave arpeggio. This way, you will be able to play the bass at full tempo (176) without having to go fast in the right hand part.
Per Sapientiam Felicitas!
