Overall a good lesson.

Chopin Etude: Improving. Need to make the beginning as calm and controlled as the end - listen to the sound first.

Chopin Ballade: I tend to avoid practicing this because I am afraid it is too hard and won't work. Should start at where it gets hard and just do it. Should try to analyse the harmonies more as they are probably not so complex when you understand them.

Rachmaninov: both preludes are better. The middle section of the Op 23 No 5 middle section needs to be more lyrical and not too slow.

Scarlatti: practice louder for clarity and then tone it down.

Onwards!
