Hi Panta,
The beginning of your sonata is so good! There are various exciting materials throughout the piece, which keep the listeners engaged. Also, the character of your sonata is enhanced further with excellent use of articulations and dynamics. I also adore your clever use of harmonic vocabulary, especially the interrupted cadence in bars 101-102 and the Neapolitan Sixth in bar 181. I am honestly impressed by your work, and you have done a great job recreating the classical style!
However, I feel that the structure of this movement is less organized. First, the exposition is pretty short, and I expect a second theme in the dominant key (E major), which is common in piano sonatas from the Classical period. From 1:42 onwards, I hear several other themes, most not previously heard, making me wonder if this is the development section or a continuation of the exposition. Another reason that I think of this is that you included a perfect cadence at bars 54-55, seemingly concluding the exposition.
Besides, near the end of the piece (starting from 4:33), I can still hear all these themes playing one after another. And the recapitulation appears to be missing: the main theme is not repeated in the end, which is not quite traditional. Nevertheless, the movement's coda is remarkable, and I really like it. Great work!
