Would I pass? (I'm pre everything)

I know look too much girl here, but I'm just on the verge of whether to accept that I may be trans man or not. I've just started to go back to trying to pass.
I can't fix my face, but I can fix my hair. What hairstyle should I go for? I have a round small face (like an asian girl's face

)
I'm losing weight at the same time so I can gain a tighter figure and so then I could gain muscle mass around the shoulders and abs more. Perhaps losing fat in the face will help too?
I was trying to pass in my mid high school years, but every time I failed miserably.

Oh great posters of manly. Give me tips and honest opinions!
