Help with the finer details

I am finishing up a romance novel that is pretty close to being done, however, there are still some descriptions that I need to really make it pop. I figured we could start with one detail and then go to another soon and pay per project. Right now I am writing a scene where they are at an amusement park, and the merry go round is pivotal for this scene. I thought we could start with a great description of a merry go round, and then possibly move on to some more short descriptions that I might need.
