I think all your characters are great. It'd be nice to see more of some of them, especially Kusa, but I know he's a tricky characters for you. For what it's worth, I think you're awesome with him when you do play him.
I don't remember anyone giving you any specific crit on Hikaru since you picked her up, so I'll offer my two cents: she's wonderful. I've seen Hikarus that've seriously overplayed either her cute side, or focused way too much on her hero/martyr complex, but you incorporate all her sides in your playing really smoothly. She's a lot of fun to play with and stalk, and I especially love her threads with Eagle.
