Really cool sound. Love that beat. I was kind of waiting for it to break out in to samba or something . I would really recommend expanding on this (the base beat) ; )

A very nice rhythm, and I just love the sound.

Although I agree with teru in expanding this, it would require something new in the mix. With these ingredients the length is just perfect. Many great pieces are ruined with stretching the length without anything new to say in sense of the music.
