I'd say this is quite well done!!! The spotlight comes on you perfectly!!
The only advice I would have is to blur the rest of the scene a bit more, as it is distracting from the main piece in the photo, which is you Or make it at least a bit less colorful, as it takes away from the feeling of the picture.
But other than that the dress is beautiful and the pose is just perfect!! You captured the "vanity" of the fair, in your posture and your expression, quite well. The way the top piece of the merry-go-round goes around your face is perfect!!!
