I started at a young 20, meaning closer to 19, so I'd probably be a good frame of reference for you. Shot on the left is a no makeup look for me a few weeks back, at 16 months HRT, for whatever that's worth. You should get quite good results, even a few that most of the folks won't get here because of your age. Be aware of them, like I got hip widening, which isn't talked about much on the forums, but can absolutely, though not necessarily, happen to you. My face, likely yours as well, hasn't reached its final adult form yet, so that possibly is still to change, and a huge one. Like, my face shape changed because of my youth, wound up getting my mother's chin, which is a female only trait, in this family. Of course, it all varies, but you have a solid starting spot, and we many years until we become a fine, aged wine, also on your side.
Good luck! Always makes me happier to see other younger folks on here.
