Cause you look like you spend more time scrapping at the clubs than meeting chicks... maybe it's just the picture, but someone looks me like that I'll get my fist ready.
Seriously tho, it's not about the picture, it's about you as a person, how you act, what you say to a girl, the personality that you convey to others... that's what makes the difference in girls that you attract...
Maybe you go for thos that give outright IOI's, if a girl looks hot and she's not getting hit on enough, it COULD be a red flag (I wouldn't go so far as to treat it as a red flag, but if other things start popping up...), even tho in experience, a single girl typically goes fishing in a bar waiting for a guy to chat her up, and are most often normal... normal as far as women go.
