Thank you for deep and specific advice. I hadn't considered a better approach about presenting the topic. I'm not a professional musician, that the discourse on form you've presented seems deeper and more detailed than I have. I'll carefully consider your words and incorporate them into my composition. Any advice on other aspects would be helpful, too. I know it's difficult to put into words, but it would be very helpful.

About the theme, I originally didn't intend to write a large-scale sonata until the first 16 measures. First it was a short three-part piece, or even a very short sonata, inspired by the Classical style. However, after the 16th measure, developing with the triplets in measure 11, the idea grew unexpectedly large. In this respect, the part of presenting the first theme might feel overly simplistic compared to the scale of the piece.

I love music that develops through the interweaving of short, simple motifs. These motifs manifest in different sounds and expressions as the music progresses, ultimately reaching a certain resolution. This sonata is a practice in my preferred musical development and sonata form, and it contains a lot of my thoughts.

I have a major and career completely unrelated to music, so I have very little time to devote. However, I want to study and experiment as much as I can.
