I'm not sure how you went about putting that together. It does sound very circus-ish. Definitely something you would hear at a circus.
My only criticism is that you should use something other than an organ and add a little bit of effect like reverb or a very subtle delay. This with give it a bit more depth. Perhaps some other background sound effects would do well such as a crashing symbol or some commotion going on. Something to also give it more depth and also tell a story.
You're on the right track, it just needs to have a little more to it.
