A minor. Again, just like the string quartet one, this one is very Mozart. I find a great use of grace notes (acciaturas) here. In the opening, you have the two hands play parallel, just like in Chopin's Scherzo No.3 . I see that after that, you had an immediate F Major Part. And then my favourite part is the syncopation with grace notes part. I think that this contains a lot of great ideas.

A major. The transition makes a lot of sense. e, f sharp, e part at the start is great, and very Mozart-like. The double-thirds runs seem fun to play! The left hand parts are very good. I think it is wrong at bar 44 to be in minor key, as that you haven't notated a natural sign. Overall, very good use of the second voice.

F major. Really waltzy. Bar 50 has a sharped C, which is a very smart choice. D minor is also a brilliant transition. I like the way it is intense from bar 56, and how it is in A minor, and transitions back to F major at bar 60. It feels magical in a way. Very great.

C# Major. Nice Introduction here. A major is something I like personally. The transitions are incredibly nice. It is smart to go back to the original key. Nice piece.
5.
G Minor. Sorry for being offline for some time. Anyways, very jazzy opening and ending, with nice transitions to different keys, as always very elegant. I like the tension in the end. Nice use of dissonance.

G Minor. March-like Finale! Very cool. I like how you used Bb Minor stuff too! Anyways, I also like the staccatissimo texture!
Overrall, 9 out of 10. Be happy! This is great, and you have a lot of potential. To improve, maybe write longer music and develop ideas. Keep composing!
