Your technique is clearly very good, and you play with confidence and good tone. Perhaps you could take some expressive liberties more than you do now (rubato, dynamics, tone variation, etc.), although I realize there aren't too many things you can do with those two particular pieces. At any rate, those were stellar performances, and I got the feeling you didn't find the pieces very challenging
I heard some audio clipping on some of the recordings, so maybe you could slightly lower the audio recoding level for the next lesson.
edit: May I invite you to take part into my musical game at viewtopic.php?f=109&t=66814
? Taking part into one is mandatory requirement for lesson 7, and it would make sense to do that now with the rest of the group playing. Postponing it might mean that you need to start your own game later on. All you need to do is to compose one bar of music, extending what has been composed so far, and play the piece from the beginning.
