What are the possibilities to better my profile? (Photos)

I have a small space between my chin and neck. What bothers me the most if the fact my jaw doesn't even make a 90º angle, but I'm afraid a liposuction and a chin implant won't really do much of a difference because my windpipe is really forward, as I try to show in the second picture with the finger. I'm pretty thin so it shouldn't be fat either. I'm also only 20 but very aware of my profile. What can I do?
