Little concert for solo trumpet

This is a short piece by my for a solo trumpet and a continuo instrument. I'd like to let everyone know, I'm not a trumpet player, and also don't play continuo often. I'm opened to receive any critic or advice to make my piece more fancy, and better sounding.
 

It's very plesant and nice. The melody is good. The piano is well used, too.

Although I'm not very fond of this style nowadays (it sounds absolutely classical) I like it.

There is only one thing I would wor over: the changes in dynamics are, sometimes, too strong: bar 23 in trumpet (from piano to forte).
