Which is More Important for a Feminine Chin? Length or Shape? - Heidi Montag's Flat, Broad Chin

Not to speak ill of the dead, but I think that Montag's surgeon could have done better when he reduced her chin. Although her original chin was long, it was rounded, as shown below. But after her chin reduction surgery, the shape was squarer and wider, as if the bottom had simply been sawed off. Good FFS surgeons would never do this intentionally since their goal is to make their patients' faces more feminine, not masculine.

But the question I posed was... which is more important in feminizing a chin? Length or shape? I am guessing shape is, because in the 1st photograph below, she's had her nose done, but still has her old chin. But in the before and after photographs, I changed her chin to make it pointier (more feminine), but also made it longer (not as long as her original chin, but definitely longer). The end result? I think the more feminine shape completely trumps the more masculine length and, as a result, she looks more feminine.
