It looks as though you are opening your jaws just a little in your photoo; i.e. to create more vertical length, or perhaps you're doing it on a subconscious level. I mention this bc, I have done this for years and still continue to do it...for so long it's become a nervous habit. I'm no expert, but I think you have what looks to be good bone structure and nice teeth. Looks like asymmetry is from the chin, small genioplasty procedure (alone) would do the trick. Just a movement to even things out. I don't think it's a problem with your jaw. You don't seem to need any (chin) vertical, but only you can be the expert on that. I had upper and lowers extracted, and I too regret it. My extractions were part of bimax process, but, still-would put them back if I could. I agree, it does create this odd spacial-void in the mouth, esp. that upper jaw.
