Will I have enough fat on my body for Brazilian Butt Lift? (photo)

I went to a consultation with a local plastic surgeon . I showed her pics of the body shape I was looking to have & she said that I may not have enough fat to transfer because it seems I have a lot of muscle. I was wondering how could people like the fist pic I'm going to add could have so little & be able to get that filled look. I'm 165 pounds & I want to be 150 during surgery . The second pic is the look I'm going for & the third pic is of me .
