This one's nice, thematic, and moves in its own progression. The lack of a counter motif was delightfully unnecessary. I personally hear this is melody to a scherzo for piano and trumpet though. It seems kind of lonely.
However, I would highly recommend you look into rest beaming to make this performance better, or change some of your 16th notes to 8th notes with staccatissimo markings. It's just kind of hard to read.
Cheers!
