This looks too big for my frame? (Photo)

To make an assessment on the outcome of a procedure we really need to see proper before and after pictures. If you don’t have your before and after pictures and ask the surgeon to forward the ones they took.
Personally I try to create a feminine S-curve when doing the BBL procedure. There is a trend of plastic surgeons who purposely do liposuction of the upper thigh in order to make the buttocks look bigger. I think this is an unnatural look that no woman is ever born with.
Ideally the perfect female form should have a perfect unbroken S-curve from the armpits to the knee.
Based solely on the single picture posted your outcome looks a little bit like a caricatures.
Best,
