Sailers results are 100% photoshopped (first two examples). id say he WAY over does it, but thats the kind of clientel he serves: those who want outrageously dramatic changes.
The negroid (technical term, not a racist) skull naturally has a more forward set jaw, yet is usually offset by a less sloping forehead and less glabella bossing. I should be careful with my words here, as to not offend, but having high SNA/SNB angles without proportionally forward set midface features (zygomatic complex, inferior orbital rims, nasal spine etc) results in the more baboonish look. and as you can see on brock lesnar, the superior orbital ridge, or "glabella bossing" is also a sexually dimorphic feature indicating high testosterone and a large frontal sinus. This evolutionally appeared in primates as an advantage in breathing (bigger sinuses, bigger airways, better survival, more resistent to breathing congestion, host of other things but il skip the bio and just say its advantageous).
I would argue that the beautiful ante face we see in people like Marlene Dietrich or Angelina Jolie are not simply a result of forward set jaw, but an entirely forward grown middle third and lower third. Trying to achieve ante face on someone with recessed orbitals and zygomas requires alloplastic augmentation, or high level osteotomies (LF3) in combination with orthognathic surgery. It is the holy grail of beauty imo.
