If you could take a frontal picture from strait on, one directly from the side, and one at 45 degrees that would really help any of us make an accurate assessment. To create a more heart shaped and feminine facial shape you could add volume to the middle of your face and taper the bottom of your face. First, you could have implants or fat injections added to your cheeks (a small amount of volume to the outermost cheek, but most of the volume in the front right under your eyes). Mandible (jawbone) contouring would thin and refine your lower face. I don't know if it's just the photo, but your upper lip looks uneven. This could also be improved with a lip lift. More photos would help, but a face to face exam would be the best next step. Good luck.
