It's good. The one thing that annoys me is the fact you break up all the phrases according to the slurs. I'm sure musicologists are happy with your choice, but, by God, you've got 4 phrases in 4 bars! And really, is Mozart such uncreative, unimaginative composer that he broke them up like that?
At least that's what my teacher fervently believes - a very prominent teacher who I find has a most excellent taste in music than just about everybody else I've encountered. "Pianists are the only instrumentalists that always look to break phrases!" he would say. In any case, why not try it? Think the melody the way a singer would - think them as one longer phrase!
But yes, as it is, it's good!
