Well composed and nice colors but just not sharp enough. This could have benefitted from a faster shutter speed or a burst of flash. Alternatively, if you wanted some blur to imply motion then you needad a longer shutter speed to pan with to make your intention more obvious.
This kind of picture works better when the subject is frozen. Work of firing while continuosly moving the camera in a smooth arc. It looks like you were trying that but the moment you hit the shutter you stopped your motion. Follow through.
