since youre young all you can really do is softmaxx. i think right now you just look sort of plain because your coloring is low contrast, meaning you have dark eyes, hair, and skin, with no contrast to really make you stand out. im NOT saying your natural features are not good, or you should dye your hair or wear contacts. sometimes especially for your ethnicity, dying your hair suits you less than just black hair. if anything, do slightly lighter highlights.
for a girl, you have a lot of opportunity to accessorize too. i like your jewelry already so you could work on getting your nails done and wearing makeup (even just lashes). those things by itself will already draw more attention and feminize you. try to always have your hair done as well. admittedly, i dont even do this myself, but doing simple styles you can sleep in would really help. hair is very important to looks. all of these things combined will just make you pop more. you have long and healthy hair, why not utilize that to benefit you?
and since youre asking, id say youre biggest problem is your eye area. you have very big and round eyes, which isnt bad, but theres not much undereye support. this is because your jaw is underdeveloped and the lower part of your face is not as projected as it should be, so the fat and skin in your midface sink down instead. it could also be the reason, for example, the corners of your mouth are downturned. because of this, though, it gives discoloration and lines around your eyes. this may make you look more tired than you actually are
doing what i said above i think will vastly improve your looks, especially for your age range
