Smooth, but as someone who actually plays jazz, not exactly jazzy. Jazz is all about the freedom of expression and the soul behind it, in whatever form that takes. Generally speaking, the majority of recordings of jazz standards are improv, that being said, those recordings regularly are longer than 5 mins. One song coming to mind had a 6 or 7 minute drum solo. So maybe play around with some ideas and really breathe some life into it.
