Hi! I’m an amateur composer that just creates pieces for fun

Can anyone give me feedback on this piece I wrote a little while ago? I don’t have any formal training in music or writing schools other than playing Trumpet in high school. So just let me know if I’m on the right track to taking this as a serious hobby.

I uploaded a screen recording of the piece on YouTube https://youtu.be/TR-ZBch8i7Q?si=r1kfrSS7Yy1guZ8q

I wrote it as a character introduction for a scene I had in mind, but just tell me how you think it sounds/how well the writing is put together
