Nataliya Kuznetsova aka (Amazonka) is a IFBB Pro with a million instagram followers.
I've gone wrong somewhere with the embedding. Facial likeness is good, but for some reason her muscle mass has been lost. You should include prompts or LORA which add muscle back. Though let's be honest - if you know Nataliya, I supsect you know a lot of about how to make muscle.
I recommend using ADetailer for best results.
