OP, don't take it the wrong way - I am not trying to 'victim blame' you and not saying your concerns aren't valid, but I think it is difficult to give advice when you are describing your issues in ways that are contradictory, it makes it difficult to understand what the problem is. So far you mentioned chimp look, punched in old lady look, and sagging facial tissues (the latter in spite of the fact that you had a large advancement so hard to imagine). I am finding it impossible to imagine what the problem is, based on your description and the x-ray (where I cannot see the chimp look or punched in look or sagging tissue etc).
I think a large part of the problem here is the fact you are Asian and were operated on by a doctor that had no concept of what is considered a good look in your particular community. I am Caucasian but happened to have bimax protrusion more typical for Asians, so did quite a bit of research on surgeries they typically do in Asian countries and saw many before and after photos from Korea in particular. I must say that in many cases, I was stunned because to me personally, the patient looked better before than after, yet it was presented as a success story so clearly what looks good to me likely does not look good to a typical Korean person etc.
For example what you mention about the bridge of your nose - I am sorry but I don't even understand what that is about, I never consciously noticed the bridge of my nose and could not care less. I understand this is important to you and the people around you but most likely your surgeon is clueless about this. I often notice that Western jaw surgeons have no idea how to work with non Caucasian people - they just do the thing they were trained to do but do not take it into account that it looks different on someone with a different ethnicity, or it is perceived differently. I am not saying this was the case with you but might be a possibility. If you really want a revision, you might want to consider getting it done in an Asian country and / or by a surgeon that really understands what your preferred look is like and how to achieve it. Maybe it can be achieved by much less invasive procedures than a full jaw surgery revision? For example, fillers in the nose, lip lift, face lift etc.
