Especially since it's a nice new look for her, right? Aesthetically wise, I just liked her with more hair since, usually when you take photos, you show off your "best", and I think of it like a photoshoot she took before she went off to battle and retied her hair XD.
But I definitely get what you're saying since her hair tied back more definitely matches her theme. Looks more clean cut and fluid. I'm just biased for more hair.
Edit: That's why I gave different options for people with different opinions. I'm going to change the picture for the splash when it comes out =3
