I personally like the echo
It's very funky. It's not bad at all. It sounds like something off an old karate movie. Jackie Chan: "HWAAAAAAAA!" (That was the sound of him kicking. I know, I did a horrible job, oh well.)
Sounds like a wonderful walk in the Zen Garden. Just a little bit of distortion, but is fine.
It would work as a song idea but the looped part is way too short and simple to be anything but repetitive. You should really take it further and spend some time creating a structured song, even if it's going to be looped.
Other than that, it sounds fresh and with potential, so keep making music!
Please contact me if you would like to use this in a project. We can discuss the details.
