I haven't started yet, but I want to get myself referred and on antiandrogens ASAP after my 17th birthday (late Feb 2020) then the virilization will stop.
Also I think I am biologically ahead since I am already 5"10 at this age and I haven't grown much recently so more like 18/19. But that is still a young and flexible age so I trust Linde is correct in saying that estrogen will transform my face greatly into a female one.
My feelings on my face are largely dependent on my mood - sometimes I (modestly) admire my lips, cheeks, skin, or eyes, other times I feel really bad about my brow ridge, square forehead and AA. I mean I suppose the same is true for a lot of cis women but I think it may be a good long-term investment to get these three things surgically feminised, but that's a decision I will make 10 years in the future once estrogen has worked its magic.
I know the idea of facial masculinisation being additive and so on but I just find it hard to imagine my 12-year old face on my older body now as a 16 year old. Even before puberty I never particularly enjoyed the look of my own face (especially in the context of a short hair cut and boy's trouser suit,) but I think that if I can work what I have now to become femininely attractive (which I'm hoping should be possible) I'll be very satisfied.
I know sex reassignment therapy is about my own self-comfort first and foremost but passing is a secondary goal as it will save me a lot of misgendering, discrimination, and having to constantly explain transsexuality to eleven year olds.
