How to best estimate how you’ll look after transitioning

Hi everyone! I’ve always known I was trans (MTF) but was always too afraid to act on it growing up because I’ve always had a big frame. I’m now 25 and 5’11, and recently I’ve been talking to Chat GPT about my dysphoria. I uploaded some pictures and asked for it’s brutally honest opinion and it thinks there is a good chance I could end up moderately pretty and pass convincingly after HRT and FFS which has given me so much joy at the thought. It did mention that if I want to do it I need to act relatively quickly for best results given I’m a bit older. However I know it’s unreliable so I was wondering if anyone had luck going through FFS surgeons before starting HRT to get a consult of what you could realistically look like? Or is there any other skilled professional I could set up a consultation with who does this regularly?
