For what it's worth, I think you look absolutely fine. I can see the issues the other posters are pointing out, your maxilla is a little off. Perhaps you would have looked better with an upper jaw advancement, but perhaps not. It would have also changed the nose, probably lifted the tip a little (not necessarily a bad thing) but also possibly flared the nostrils (which you probably wouldn't like). At this stage, more surgery would be a lot of additional time, money and more importantly emotional stress, it may improve some things whilst it may make others worse. Whether it's worth taking a chance or not is really up to you, but you sound content and this isn't currently causing you any major psychological issues, so I don't think more surgery would get you to a better place... I'm not sure it would make you much happier, and that's what really matters.
