No, it doesn't sound like Mozart and certainly not as a Menuette.
It is too forceful, like some marching band. Lower the velocities of the accompaniment celli and basses, make the violins sing at the higher registers and try to make it sound like a chamber orchestra.
And listen please to a professional recording (NOT the Berliner Symphoniker with Karajan!!!!!) to find out what I meant by this. Mozart didn't write for large orchestras (there weren't).
My thoughts are may be a bit hard on this, but you asked for it.
The first half of the phrase is not fluent enough, the second half is a lot better (2nd half does not refer to the 2nd repetition, of course). It might be solved by having a higher tempo (but I like my Mozart light and fast, and not everyone does), and not having a slow attack on the strings, but rather a fast attack and fast decay on the beats, like a accented notes, more punctuated. But ... I'm not completely sure of it. It's a rather difficult piece because of the restrictions the melody places on the rhythm. I imagine a gracious dance with small, fast movements of hands, twists, etc., on beats 1 and 3.
Much better. You are fast!! I have the complete score next to this reply window, so I can comment on the whole thing. As I see, the 1st and 2nd violins are doubled by the flutes and oboes. I don't know if you used the score with clarinets, if so then those clarinets also double the violins.
Doubling means here, giving those strings a "power jump" to make them sing a bit more than usual. Don't overdo those upper voices and lower them a bit. They are just there to "enhance" not to "rule over". The fagotti (bassoons) play more or less them same voice as the violoncelli and contrabasses. So they are doubling the lower strings.The only voice that stands out are the violas. They play a harmonical role, to fill in the chords. Give them a bit more "juice" to be heard.
Also, and just experiment with it, use some legato in the violins (those 4 8th notes at the beats 2&3/bar 3 etc. - integral part of the melodic structure), to stand out against those "rhythmic" quarter notes. The non-legato doubling of the woodwinds will give that dub-dub-dub-dub sound as if they weren't legato.
See this. It is a score with clarinets and oboes at the top. Different version of the same work. Starting with Flauto is the original score.
