I love fat transfer and perform it regularly. To me you look very young and I think you have nice features. You natural anatomy shows a large deep orbit and orbital rim that may benefit from volume but maybe a little later in life. That being said I have performed fat transfer on very young patients to add dimension and shape in various areas of the face and they've been very happy. I'd suggest some Restylane first so you can see what it might look like. Restylane injections are both temporary and reversible and would be a good low risk low cost option to try first.
