omg love it!!!
they all look great... and the outfits are really cute. the colors look good!
i used to hate the re-used colors, but i like them here.. maybe since Gaki's color isn't represented (that was somehow easier than saying Gaki isn't here anymore
) they look more symmetrical. especially since i can kind of see Haruna's color being like a dark orange.. if you darken orange the right way, it will look brown (chocolate, sorry Haruna!).
so that would make Riho's the only original color, and since she's center it works fine!
the only thing i would change about these outfits are the skirts.. maybe a similar but better pattern, or just constructed in a way that makes them look more finished. but i'm okay with them as-is too and i'm feeling much more optimistic about this single now.
edit: oops, forgot about Eripon.. she's too hidden back there. xD so i guess purple is also an original color now. hope the next girl that gets light purple is someone i like! but that usually never happens..
