I have no idea what your voice sounds like and what your mannerisms are(me for example, my voice is reasonably chest driven but my mannerisms/look are too andro and flamer-y) but dear god, no, you do NOT look like a woman, not to me! If I just saw you across the room, even if I didn't think 'man', I wouldn't be comfortable assuming you're a woman, either, and that says a lot- to me, there's a big difference between 'DEFINITELY CHICK' and 'hmm... not sure, better not assume', because it leaves your ground open for you to gently correct anyone who may be confused. (For example, I had a guy walk up to me the other day and ask, 'are you a man or a woman?' which may seem like a downer they don't automatically assume 'man', but really, it's a plus, because one can dispel doubt about manhood.)
You have a pretty aggressive look, the first shirt may have been 'femme' but it's not like you're wearing a friggin babydoll tee. I'd say you have the man-look down enough not to need to stres about it a whole lot(plaid and button downs really help with a masculine look, but really, if you don't carry yourself well, I've found I still just end up upping my dyke-dar, not my man-radar) and your face is more handsome than femme/'pretty', I don't know if you're on T yet, but if not, consider yourself blessed with what you have to work with.
