well, Wishy, I'll give you my honest opinion. The only thing female about your face is your chin. The rest is typical of the face of a young male. Based on your face, I'd say you shouldn't have any trouble passing. If you aren't passing, it must be due to your voice or something.
I know you posted something about the fat on your cheeks and wrists, but I'm really not seeing that as a problem (course I can't see your wrists lol). The placement of your eyes, nose, and mouth is all typical of a young, small male. (believe me, ok. I know what I'm talking about, as I usually go for short, small framed, baby-faced guys.) The chin really is not that off, it's just the only facial feature I could come up with as feminine.
