Keep practicing and you'll get better... but this just needs a lot of work.
not that great, to be honest...
it started out sounding phenomenal, but after that it was just sort of a letdown. I mean, the trumpet sounded like somebody just playing random notes in-tune with the song's rhythm, but not the right notes. like somebody who doesn't know how to play the instrument.
so, yeah. it could use some fine-tuning, but that's no reason to give up.
