How to find out if you can pass
Asking other people if you would be able to pass is problematic since that requires you to share your face with these people outing yourself as potentially being transgender. Then there is the issue that other people who you ask might be wrong or not give you a honest answer.
What i recommend instead is trying out crossdressing and makeup to see if you can get close to passing without HRT, if that is the case you should be able to pass ok just from HRT, otherwise you will at best need facial surgery to pass and at worse not even facial surgery could allow you to pass as a female.
People sometimes ask me if they think they could pass and when that happens i do give my honest opinion, unfortunately that once made the individual who asked me very upset causing him/her to leave my discord server and attack me (even though i explained beforehand that i am not good at evaluating if people could pass), my assessment was that he/she would need FFS to pass as a female despite just being 16.
There are also other traits besides your face than can out you to other people. If you are taller than around 185cm as a male your height alone can out you as having been born male. You might lose around an inch (2.54 cm) from HRT but that's different for different people.
HRT will typically affect the hip bone development if initiated before age 24.
