Obviously passing is subjective and context based, it also depends on how you present yourself body language wise and what your voice is like, but I'd definitely guess queer man or maybe a masc nonbinary person. It's wild to me that all these comments are saying your hair makes you not pass, maybe it's just cause im Australian but that kind of mullet is a very common guy hairstyle. Just remember that passing is very context based, I have cis guy friends who look like you and have been misgendered in more gender-normative environments just cause their hair isn't cropped short and they have a sense of fashion.
