Is this too big of a chin for females?

[bbmray]

I have an overbite and am getting a double jaw surgery with genioplasty with this surgeon, but some of the past surgeries look like this, are their chins too big? Do I need to specifically request a smaller chin?

Their chins look great.

The outcomes (including the chin) are on target with good aesthetics.

These chins and jaws look more beautiful to me but I don't know a lot about aesthetics so I don't know why, is there a difference I could describe to a surgeon or am I missing something here?

The afters from the doc all look very good and those private photos are not good for comparsion. Different angles, different light, etc. And they also look like teenagers, more juvenile.
