why is my jfa not a straight line and sharp if my mandible straight on side profile?

[Pubertymaxxerr]

from the front my jaw looks a little rounded. i am about 15% bodyfat so going to try lean down to 10% but i dont understand because my side profile my mandible is long, forwardly projected and straight (sharp essentially) but from the front it looks like i have the jaw development of an ltn, curved
