I find the recapitulation A little weak.
The bridge beetwen the themes is too smooth, most of the time that would be good, but in the case of sonata makes it lost contrast.
I liked it overall, maybe it is a sonatina due to his duration.
If you want to, you can make a repetition of the exposition, that helps to stablish the tonality and also helps in the lenght xd.
Sorry for my bad english.
