It's interesting to put the chronology of your piece into the "About Me" Section. I take that idea and do one myself. It's also because of that I discover your first post here.
I only listened to your 1st Piano Sonata in C minor, so I will just review it first and review the second one later.
The main issue here the structural problem and coherency of the piece. I think the piece can be renamed as Sonata quasi una Fantasia to reduce the problem. I think the issue identified by @SSC fair, especially under the genre of sonata. I myself will think sonata as a narrative genre with underlying narrative structure. The appearance of motive should be incorporated to the structure to provide coherency, favourably in sonata form. Sometimes the reappearance of motive doesn't provide the coherency, either within itself, or within the interactions between themes and motives. But I also know that your style is to have the music's affect and emotion happen right at the moment, and I also love that too since that's what I cannot compose. That's why I think the title "Sonata quasi una Fantasia" more appropriate, instead of just an ordinary sonata.
I would also like the bar number reset during the beginnings of each movement. That will be more clear.
I think the motives of the first movement easily recognizable, and I enjoy how flowing it is, even though there's no clear direction, thus making it like whirlwind. I only find bar 107-108 quite awkward.
I love how dense the second movement is, and the opening wave is interesting.
For the third movement, that's my favourite movement. I think the up an octave sign of the treble clef not clear enough. I think some of them can have indications of up an octave lines while others are not needed. But it is really cool, especially the cold and cruel harmony. Is the theme in bar 261 borrowed from the second movement of Schubert's second piano trio? That sounds familiar for me, and I love it. I also love the use of left hand melody in the movement, so deep and introvert.
I will look through your second piano sonata once I have time and energy to do that!
Kind Regards!
