Completely agree with Dogmatix, you are a pretty good looking guy and jaw surgery is expensive, painful, time consuming with some bad risks involved.
Jaw surgery involves sometimes long stints in braces and alot of appointments.
I think you have some attractive & masculine facial features and I'm struggling to find flaws in your face.
I think your good points are
-wide cheekbones
-wide jaw
-good chin projection
-good nose shape - Nose base isn't too wide, nose isn't tipped up, can't see into your nostrils, symmetrical, bridge isn't overly obvious
-good teeth
-ears aren't flared
-nice eyes - eyes are same level, same size, nice shape
If you are really wanting to be pedantic I thought you had one facial flaw
-the midline of your chin point appears to be slightly to the left of of your midline of your face. this might make lips appear askew when you smile.
Yes maybe your face looks slightly full below your cheekbones? Maybe weight loss can do something for you. I think some fat on the face is good though. From the 45 degree angle photo your lips look like they protrude slightly, maybe you have some teeth protrusion which is perfectly normal in some races. I think fat loss on the face might cause your lip protrusion to look worse and can make your nose look bigger.
I would find other things to worry about, maybe take dogmatix's advise and get a haircut haha dye your hair or something
