Itsuki is so the best part of this image.

Well. Maybe a close second...

If I were Kyon I'd do a facepalm.

Sort of shoe-horning the characters in there, but I guess there are some personality similarities if you look hard enough.

I'd say Haruhi goes more with Ritsu and Nagato with... no one.

Mikuru isn't like Tsumugi at all, but they have similar looks (moeblobs, long hair with similar form, well-formed bodies). I'd say Tsumugi, Mikuru and Miyuki (LS) could be twins.
