Well, most surgeons will discuss options for you, they have an expert eye I think. If you send pics to someone like Suporn in Thailand (there site gives directions on what pics they need) they can give you suggestions to what facial surgery they could do for you. Suporn does rather subtle work in my opinion, which is great. You don't come out of it looking like you have had facial surgery, but then most surgeons probably are pretty good about this now, as long as you choose someone reputable.
Might as well get it all done at once, as recovery is a bitch for face surgery I reckon, particulalry bone work.
But I think hormones should fill out your lower face more which will make a difference. I think being a little gaunt in the lower face detracts from your femininity.
See how the mones go. Other memebers had rather square chins too, but they came out looking great after hormones.
I think you could do a lot without surgery, so my suggestions are:
Get a hair cut with layers that frame your face better, run some irons through it to get it nice and straight. It seems a bit unkept for what you see on most girls. You have probably been growing it ages. You could go with really strong bangs, straight accross. That would look fierce but needs a bit of upkeep. Or leave them longer in layers.
Also you could shape your brows a little more, maybe go slightly thinner,
Go easy on the eyeliner, go a bit more subtle I reckon, like line just a third or so of the outside corner, or go with a lighter shade. Your eyes look nice and big as it is, I think they are a great feature, but a bit of eyeshadow blended into a lighter shade on your brow bone will really make them pop!, even a little color on the lower lid to line it, again maybe just the outer third, but have a play, I'm no expert. Get a lesson. My lesson was one of the best things I ever did. I just asked help doing a simple day to day look and it made all the difference, and it is easy to play from there.
Best of luck honey! I think you are gonna be gorgeous! You already do have a super girly profile, love it.
