Options for for face/weak jawline? (Photos)

Hello, I have attached a few photos of my face. I quite like my face head on, but I have an awful side profile, from what I presume is an underdeveloped jawline. I have had people point out to me in the past that I have a very flat face, and it has always bothered me. I'm just wondering what options are available to me looking at the photos attached? Thank you.
