This is just another short instrumental by me...

Well, overlooking the quality of the recording, and the fact that the song is no more than a noodle...

It's a nice riff. I like where the time signature changes. It sounds like you've got a good sense of rhythm, that is, you didn't hold any notes to long or short. which is good. especially for someone your age (guessing 9-10 based on your picture.. but I've been wrong about that kind of thing before...)

It's a long way from becoming an actual song, but good work.
