This looks too big for my frame? (Photo)

Ideal buttock size and shape is a very personal and opinions will vary with everyone you talk to. Most important is if you think it is too large. It does seem a bit overdone to me. If you would like it reduced, it is fairly straight forward to do with liposuction to revise your buttock. Good luck.

Dear Niyahlove13,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Based on the 1 side view posted photo your buttock is larger but it is a very personal decision to have this new surgery - BBL REDUCTION. There are 3 boarded PSs in USA offer this surgery now. Fee from $6,000. Best to virtual consult with...

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,
