The others are right. Contour for the nose - ice possibly too - and if absolutely necesary see if any "exercises" work to debloat. Originally I was going to recommend losing body fat, but it could also take away the slight curves (roundness, I suppose) on the cheekbones and lessen the cuter, more feminine look that I assume you're going for. Now idk if you were only asking about the face, but personally I think french nails (or similar) would fit your aesthetic, just my opinion. But overall, lovely facecard, good for you.
