Mario, Pikmin, Master Chief... What characters look like doesn't matter and never mattered.
And even if it did, seeing the main protagonist of this game as "ugly" and "masculine" just because she shaves her head... I mean look at her face, she's a very beautiful woman, and as long as I don't mind being surrounded by NeoGAF homosexuals, I'm still quite surprised.
Having hair or not does not erase your beauty, the harmony of the lines of your face. It is also a proof of beauty, if you are beautiful without hair you are beautiful in any situation, especially for a woman.
And anyway in the end beauty is subjective, to a certain level. As a person attracted by women I think she's pretty. In the same way that most of GAF users, who appears to be homosexuals, are attracted by guys like Nathan Drake, Kratos, or I dunno, Ryan Gosling ? Tell me guys.
