Maybe it is not easy to describe accurately about how you want your photos to be. Then the Reference Picture can help you better describe how you want this project to be done. For example: If photosedit.jpg has similar effect to what you want your photo to be, you can sent it to our service department as Reference Picture and tell us in the Project Instruction, e.g. "make my eyes the same as the girl in reference picture photosedit.jpg". That will in great help to reach your goal.
