Galbrena looks good so far.
I liked Gunslinger style in DMC3, and I think this is clearly Kuro's take on that with a bit of Bayonetta mixed in (particularly with the moves where she shoots the pistols with her feet).
That said, I'm not a fan of the dual pistols though. It's already overdone in this game. She should have used a machine gun or maybe a sniper rifle (since she's an assassin out to kill Elfy Welfy and all that) or a shotgun to distinguish herself from other pistols users. But I'm fine with what I see so far. I think I'll roll her.
Qiuyuan on the other hand I don't like.
Which is a shame because I liked his wandering ronin type design, but I hate how his attack animations involve him doing these retarded drunken sways. There's that one move (I believe it's the third hit of his normal string?) where he turns around and drinks his sake or whatever the fuck is in his gourd after swinging his weapon. And then after the final hit of his normal string, he does that drunken stagger, which looks shit (not in terms of animation quality, but in terms of style and my preferences for what I look for in animation). Obviously, we haven't seen some of his moves, but for me, if I can't enjoy a character's normal strings (you know, since they make up like a big chunk of the character's moves), then I'm not rolling the character.
