how much side profile matter?

[SixCRY]

It's not the side profile that is important but the definition of jawline

Side profil is an indicator of lower third definitionn

Hyoid bone position is important from every angle , but the profil is what indicate you the hyoid bone position

you can hide more failos looking directly from the front

side is more like what you look irl and your irl looks matter more

you can have a good front but low hyoid for example and you look subhuman no girl will find you attractive

Indeed, I bet no girl ever found this subhuman attractive because of his low hyoid and recessed jaw

Front and 3/4 are probably equally important, as those are the angles people see you from 95% of the time. Side profile is cope. Front might slightly out-edge 3/4, as you can't have all your Tinder photos be from a 3/4 angle, that just looks weird.
