I'll describe what I can, but as I said, these both were rough edits so I wasn't being very scientific.
First, I used your VFFS image as my starting point. There seemed no reason to redo the work already done. I could try to describe the differences between the original and VFFS image, but believe that you probably already have some sort of an analysis regarding that.
Now, for my own work.
I left everything above the columella alone. Assuming fairly average anatomy, I positioned the upper lip high enough that the teeth would probably show a bit when you speak. The shape of the mouth in my edit remains the same. After an actual lip lift, the top lip would probably look a bit fuller when looked at from the front, and the corners might be slightly lower than in my edit. I did not try to emulate this.
Since mandibular bone work has to be done where it doesn't pose a danger to the nerves I mainly reduced the chin height under where I believe the mental foramen would be. Although I did not have a profile picture, I assumed sliding genioplasty to also shorten projection. This alone would probably make the chin too square, so I also smoothed the lower contour to maintain a smooth profile.
My primary goal was visual harmony between the positions of the nose, mouth and chin. I noted the resulting percentages in my previous post.
I'm sure you are aware of this, but when working with a picture in photoshop, the surface results are automatic. In real life, it's possible that reducing the bone to the extent shown (at least in my second edit) might require tightening the skin/soft tissues to avoid looseness.
I hope this is of some help...
