You have a decent side profile I'd say you're ltn but that's not bad for your age because you're going through puberty, you could do with a thicker neck you could do this by doing neck curls training your neck and then I'd say you have underdeveloped zygomatic bones and mandible extrusion isn't the best they both can develop through puberty so I would wait a while but if you are impatient you could bonesmash your zygos this doesn't normally increase the actual bone mass but can give a 'pump' and create the effect of bigger zygos it can also create hardened tissue around the bone I forgot the proper name for it though I wouldn't recommend bonesmashing mandible as it can offset your symmetry a lot more and it is easier to injure yourself. When you are older if you haven't developed I'd recommend injecting test and hgh to influence extra bonemass( do this at the point your growth plates are still open but you have pretty much halted growth) and then you could maybe get fillers or implants if that doesn't work I'd say with your base you have HTN potential to get 18-20 after teen years. For now stick to sleeping well and eating well so your puberty processes do not suffer
