Just looking at your picture I would say you have wonderful passibility potential.
A few things to note.
Your skeleton hasn't quite fully fused. (This takes place between 18-25).
What this means is that under the influence of hrt there is a possibility to change the physical ratio/shape/size of your bone structure, including hips. This is a closing window, one that many of us missed, including myself.
Facial hair. Hrt won't decrease any current facial hair, but will prevent new growth. Most girls here end up having to go through electrolysis which is hundreds of hours of pain and often over $10,000 to remove the hair. If you have little facial hair now, and start hrt you could use the majority of the money that would have been needed for electrolysis for a trachea shave and chin reduction/FFS.
Your shoulder width will change for the better during hrt. Hrt has a massive affect on muscle tone. Many believe they have massive shoulders, that once on hrt appear to melt away.
Hrt will help with rounding and softening of the face, and can change your overall body shape due to both fat redistribution (a misnomer as fat does not technically move, but you're body's preference for what areas of the body to store and use fat dose change).
You can try HRT, and if you find it's not for you, you can stop. There are some permanent changes that can happen over longer periods of time, but most of those can be reversed somewhat by stopping hrt, or surgically. I.e. Breast growth.
There is always a possibility of sterility that may be non reversible under hrt as well. I was told the higher transitional dosages for hrt have a high risk of sterility after nine months.
My suggestion would be to seek out a gender therapist if you haven't already, consider a low dose of hrt, or even anti androgens to minimize any additional facial hair growth, and be mindful of the window before you're bones fuse permanently.
Again, your potential to pass is very high. The more things that indicate "female" with your presentation the more likely others are to completely ignore anything pointing to male. The brain is funny that way, that we don't perceive reality as it is, but how we think it should be. The brain often completely ignores details that don't fit with the expected perception of our world.
I have tons of experience with this, where I had to force myself to lean into the male role before transitioning to avoid male fail. I've had times where I was dressed in all typical male attire, had stubble on my face, short hair, and still got gendered as female.
TL;DR hrt changes your appearance, including ratios, face, shape, etc. You can stop hrt at any point. The younger you start hrt the better outcome that can be achieved. Consider the window before bones fuse (25 years of age).
