Hello mariela_mentizi_photo . Not bad composition at all. Maybe adding a bit more saturation and details. Also I would recommend to try to get closer to the subject, it trying to manipulate the leaf till you get the unique photo.
Good color composition! The picture and the idea behind is really good might can be improved as Jack mentioned already.
Maybe you can try to change the perspective and play a bit with light and shadow (if the sun will be there).
