If yor really want me to give you my honest opinion.
Well your a bit obese and have male fat on your face. I suggest you go on a healthy diet and start excesicing before starting HRT because it will much easier to get good redistrubtion if you do.
Also it will increase your HGH. In fact I heard that there was this one girl that wasn't blessed with genetics and HRT wouldn't respond well because of that. Well, she ate healthy, excersiced and it worked VERY well on her. She looks like a GG.
If you smoke, drink or do drugs- stop that...
Judging by your features
1) Your skin isn't that rough. You don't have much facial hair if any. Doesn't look like you get a 5 O Clock shadow. According to that- I'd estimate that your skin will come out very smooth, soft and your current facial hair will very likely soften, lighten and grow slower.
2) you lips are a bit flat. GG's do have flat lips so nothing to worry about. HRT can make them fuller though so you still have a chance.

3) You jaw isn't too bad.
4) Your hair line is very good- you aren't receding at all. HRT in my opinion and estimate will make your hair much fuller and thicker because your aren't balding.
5) Your bone structure isn't too bad. I think you have too much fat on you- that's why it's hard to see your bone structure on your face.
6) You nose isn't that bad- I've seen worse. A girl on this board had her nose changed A LOT. It got thinner. I think you have fat on your nose and it's likely to change.
7) Well your eyes are a bit small BUT HRT can make it bigger somewhat.

Your neck is a little big but I can tell you right now that it's all becuase of the fat.
Last Note: I visualized you without male fat, and year after HRT with feminization. To be honest, I think you will look GREAT. You don't look that masculinized(however you spell it). I think the MAIN problem you have is male fat. My suggestion is start doing cardio, yoga, stretching etc... Don't wieght lift though!- It will increase your T- you don't want that! They only problem I can see in you right now is your fat- that's really all.
Your shoe size may decrease due to fat and muscle loss, your hands too..
Tell me your hieght and wieght...
People's Reaction?
They will not recoginize if they don't see after a while and people that see on a regular basis will wonder what's going on.
Some people are SOO slick & smart that they will know what your doing...LOL. it happened to some people here...Your breasts can become quite noticable. Your previous clothes may not fit you well. You may look ridicilous in male clothing. People may stare because you may look a bit wierd.
Women will notice first though.
So far I haven't gotten any of that though but my aunts and mom are asking me what I'm doing to my skin, why my acne is gone and why it's looks softer...
Some people can't pass as male after 4 months, some after 2 years, some after many years- it depends really...
