yes your style just screams GIRL!!!! just by looking at your style and how you color things. Your subject matter too. Girl girl girl girl girl. Nothing wrong with it though, you're a good artist just like many other men and women.
Seems like you're suffering from some internalized sexism.
Depends on the picture, but I would thiiiiink no? Sometimes, especially already knowing you're a girl, the eyes and detail there makes me think "female artist," but it's hard to say, since that's biased cause I already know!
I went and had my sister - who doesn't know you - look through your gallery and I asked her, and she was indecisive but ultimately decided "no" so I vote no Her reasoning was that your men and faces have a great masculine set to their faces, especially in their jawlines, which is something drawings that look like they've been "drawn by a girl" distinctly lack, at least according to my mental stereotypes!
