Unhappy with my face shape (prior jaw surgery), how do I achieve better balance?

I dislike my narrow face and long midface. My forehead feels flat and my lower face seems to protrude forward in a profile view. I had a sliding genioplasty to my lower jaw, along with a chin implant when I was 17. I don't know the name of the doctor or type of implant, but I feel it was not the right shape for my face. I have a large dip between my chin and lower lip. I also am in need of a rhinoplasty to address the bump in my nose. Any suggestions to achieve a more pleasing shape?
