Why does her BBL look so botched ?

Gnat and Britney from GNB got their BBL's around the same time I believe. But Britney's BBL looks way better !!! It actually looks more natural.

Gnats BBL looks more botched every time I see her. Her waist to Butt to thigh ratio looks so off. I just wish the would have stayed with her old body. Her BBL looks terrible.
