K. 331, eh? I was supposed to learn that piece when I was 13 and in 8th grade, but I never nailed it down, so to speak. I think in the opening theme, you need to achieve a more flowing quality. I don't see any staccato marks over the chords, but you play it as though there were. I hope that isn't something your teacher is putting you up to. On the minor variation, I'm going to get after you just the same way my piano teacher got after me -- not enough legato in your octaves! I thought to myself, "as if playing octaves with one hand and when they're connected by sixteenth-note flags weren't hard enough, she wants me to do it legato?". But despite these suggestions, I think your work on this piece is coming along nicely, and I hope you end up doing it all the way through, and with the commendable degree of accuracy you've shown so far.
