The girls are right about the smile thing. You don't need to have a grin like a Cheshire Cat all the time, but... ok actually maybe I could put it a slightly different way - you need to soften your face. You can still look serious but in a gentler, softer sort of way, if that makes any kind of sense? I didn't see any mention about if you're on HRT or anything yet, but if you're not (or you're just starting), then that will most likely do most of that work for you too

In the meantime try what the others said about the subtle "girly smirk" because it does help a lot

What I think is really the problem though is your hairline - it's got that male squareness to it and exposes a lot of your forehead (female hairlines are lower and have a more rounded shape to them, whereas mens are higher like yours and either square or M shaped (my unfortunate affliction, so you're doing better than me at least lol

). If I cover up your forehead / hairline with my hand, I'd say you pass 100% in all those pics in spite of that "hard" look I mentioned above.
FFS of course can sort out the hairline and in your case it certainly doesn't need much work, but in the meantime you may have to consider working in some bangs to your hairstyle to cover the hairline / forehead. Alternatively there are clever visual tricks you can do with makeup to distract attention away from it.
As for exactly why you get such mixed opinions, it may be as simple as the pics you're showing people / the pics various individuals are choosing to focus on. In the pics you've posted here, some of them you'd pass and others you wouldn't. Take these two for example:


In the first one, the light source is behind you and you're silhouetted quite a bit. The contrast between your forehead and hairline is quite low which makes it a lot less noticeable, which in turn (if what I've said above is correct), makes you look more fem. In the second one the light is in front and the contrast between your forehead and hairline is quite high, highlighting the more masculine shape of your hairline far more than in the first pic. If I'd chosen to focus on that first pic, I'd have said you pass. If I'd focused on the second, I'd say you wouldn't. Hope that makes sense

Anyway hope that helps and point you in the right direction hun
