First of all, I'd like to say that I think you're a fantastic player. I love the way you play all of your characters, and I think it's especially impressive since your characters are all very calm and could potentially be a little boring in Kiseki's setting, yet you manage to make them all interesting and fun to play with. So yeah, your characterization is amazing, keep up the good work!
The one thing I've noticed is a really small thing. I've noticed that sometimes, your tags tend to be a little short and hard to respond to ("thank you" or "I'm glad you think so" etc). It doesn't happen that often and like I said, it's not a case of bad characterization in my opinion. It's just be something to watch out for, I think.
