Hi txina,
Welcome! I see the asymmetry, a set back lower jaw, but I'm not sure whether there's a gummy smile there or not. Is there? Also, in the last photo, is that where your jaw naturally rests?
I'm in no way an expert -- just a post-surgical patient. I would ask your surgeon about the potential for lower face lengthening. Surgical forward movement of the mandible tends to widen and lengthen. The degree of which would depend on how many millimeters it's moved, however.
With upper jaw movement, I'd ask questions like: affects on "tooth show" and changes to nose (widening and upturning).
I had some asymmetry, as well, but this was not addressed by my surgeon. On me, it is more pronounced post-surgery. I would make sure yours is corrected and not overlooked.
You look good now, so I understand your aesthetic concerns.
Good luck.
