Excellent photo! Love the contrast between the silhouette and the sky. All the details you can still see - the slight ruffling of the shirt, every bend and slight curve/bump in the shoes, and especially the hair and how it's wild and fluttering in the wind. That against a gorgeous backdrop of a sky, slightly dark yet colorful on the one end, growing more light and bright towards the other end. To have the subject jumping from the dark side towards the lighter helps deliver the message of "Freedom". That combined with the fact there are no other objects, no other natural landscapes captured, just sky and a silhouetted jumper = wonderful photo.
