Nice sort of themes you have for the characters and their writer/artist teams:
cpl_crud has described how he relates to Hanako in a vaguely paternal way and Weee being as young as she is fits into the image almost as a friend or acquaintance of Hanakos'
A22, Moekki with Shizune definitely give off that "me against the world and the world is in trouble" vibe
THM, Pimmy and Emi got that sort of "healthy living" feel to it.
Suriko, Raide and Lilly with the tea, fancy dress and extended pinkies just scream "elegance"
(either that or, "ain't no yakuza here. check the other tables...")
Aura and Kamifish being painted by Rin sort of has a touch of the creation creating itself from inside the depths of the artists mind
