It seems like you are able to become one of the winx girls but first you have to select your look. To do so, click on the hairs next to the images for the hair, clothes, accessories, shoes, face, and wings. There is a large selection so just go through them all until you find a look you like. Once you are able to pick the look that is just for you why not try finding a background that your winx girl would look great in. Once you've finished your look, you can either start all over again or just end your game.
