Concept for another character (not named yet) I'm working on...she is a warrior, but a very wise horticulturist as well, protecting and overseeing a very beautiful garden belonging to a royal kingdom.
As far as the face looking male, you should also arch the eyebrows.
Nice work, besides for the last comment I think is well done. Just touch up the chin a bit and I think it would do the trick, if not hey she just works out a lot so that is her excuse!
The face looks to me more like a male's face, but otherwise its a fine drawing.
