Everyone is so
hidoyoh! or whatever it exactly is :P i just love that word, especially if Nayuki says it.
As for your sigs. There all very dark. And the Suigintou one has odd edges at her hair. Which usually is the result of rotating/resizing to much. At least from my personal experience.
Though your avatars look nice and unique as a style of your own. I like the avatars that has sort of one color tone in it. For example the pink version. ^.^ And the different edges on some of them. I usually don't spend much time on a ava beside just cropping it and slapping a cheap border over it
And heh don't worry about triple post. It's a sin most of us will have to commit in the Fan creation section
