Is my doctor going too big with 560cc silicone? I am a small C cup with 350cc saline implants (previous 34AA) (Photo)

I am 5'5", 135lb, 21, a small C cup with 350cc Saline. Switching to silicone for the softer feel and a cup size increase to a fuller D. I want to keep a natural look but still have larger breasts. I do not want round, fake, stretched breasts. I do want full breasts with cleavage which I do not have now. The chest tattoo photo is me now, and the next two are goals (sort of).
