Yep, Star girl is best girl. I imagine her shooting homing lasers (like Gunbuster) , transforming her star pin into a giant star boomerang and obviously using a star shaped beam.
I imagine same face can be difficult to avoid in most animu styles because the nose and the mouth tend to become just lines. Is it just me or are your chins getting pointier and pointer. I am seeing differences in your faces, specially in the upper part of the face.
