I know you worry a lot over your characterization, but I think sometimes it... doesn't work in your favour, in that you seem to be holding back a lot, and I can't imagine that's very nice for you. You do a nice job of rendering your characters' voices, from what I've had the chance to read of them (most of my exposure's been with Ben, whom you know I live ;o;), so maybe just get a little crazy with them?

You already mentioned your activity, so not going to touch on that - I think it would probably help to make some more new CR too. At least, in my experience, it goes a long way to do that when reintegrating a character (set). /o/

But, seriously, it all comes down to Arg. the First: let your hair down a bit more!
