What procedures can I do to my face to get rid of the square shape and saggy cheeks? (Photos)

I love the face of this one woman and I want to change my face to look similar. My face shape is square and I want an oval look. I've had fillers done in my chin before and liked the result but it’s temporary. I asked about chin implant but 1 doctor said it won’t look good because my chin is uneven. I also want something done about my cheeks because they sag. I want to do anything that will help me look like my goal picture. My main concern is my shape, cheeks, and chin, nose. Lost of fillers.
