Congratulations for this enjoyable and galant short sonata! It is nice to see such an easy and playable piece which comprises compositional skills to let it sound in the mood of the late Baroque era.
Allegro
An easy to play but clearly structured sonata form movement!
I especially liked the phrases with the syncopated, perhaps staccato eighth notes in the second theme in bars 17-18 and 21-22. To make this second theme even more colorful and to avoid the tendency of repetition, I would try to vary bars 13, 15, 19 and 23 slightly, for example by introducing more counter-movement between the voices, at least in some of the repetitions.
Might be that the finale could be made a little more elaborated, for example by creating two variants for the last few bars, so that in the repetition there could be some more ornamentation when reaching the final chord.
Some aspects regarding the playability and “aesthetics” of the score. Measure 31 should be moved to the first page to avoid turning the page, which is only necessary for one measure here, and I would try to balance the distribution of measures between the staves so that the last staff does not appear so stretched out.
Andante
Serious, with slow rhythm, but also with a dancing character, perhaps an Allemande.
I would avoid the octaves between bass and treble in bar 4, third beat and bar 5, first beat. Perhaps the bass could be in mm. 4-5 as | D E A Bb | F C# D F |. The same in bar 13, first beat (G instead D).
Minuet
The minuet is another superb example how an easy piece can be expressive and full of character. I love the articulation and ornamentation which unmistakably emphasize the dance-like character of the minuet.
By the way, I think I have recognized some more or different ornamentations in the recording than in the score, for example in the repetition of bars 7 and 15 of the minuet and the repetition of bars 4 and 6 of the trio. Is it a live recording or, if not, did you have to realize all that ornamentations in your notation software „by hand“ to achieve that realistic effect and the distinction between the different occurrences of the section due to the repetitions?
I ask this because I do the same thing when writing a score, having a „print“ score and a „midi“ score achieved through „if-else“s in the same Lilypond source code. (Yes, I have seen in your profile that you are one of the few composers who also use Lilypond ...)
Rondo
At the end the fun, the fast rondo.
Here, I would assume that this is not a live recording, which would bring to the piece the intended lightness and elegance with more soulful phrasing - that the composition undoubtedly contains.
When reading the score, I was initially somewhat confused because I could not see the upbeat note that introduces each next phrase. Therefore, I would divide the two eighth notes at the end of measures 4, 13, 17, 21, 25, 29, 33, 37, and 61 into separated ones that are not connected by a beam.
