Hi Daniel,

All of these have considerable melodic interest and are tightly structured. I find the length curious. While a composition can be the length it wants to be, these seem more statements of themes than fully realized pieces, especially the first and second, while the waltz seems a section of a waltz, still wanting, at least, a middle section and recapitulation. But I've always thought Chopin's A Major Prelude wanted to go on, too, so I wouldn't take my perceptions too seriously. I did enjoy the pieces.

all best,
