Sakura looks rather frightening. She has a very dark expression, and the way her claws are right over Mai's head in such a way convey a really interesting kind of sibling relationship--It's almost protective, but it's also kind of threatening. Very interesting.

Lovely coloring. Colored pencils, I presume? I'm very impressed with the soft tints on their kimono, and the little patterns on them are lovely. Another interesting difference between these two are the way Sakura is wearing all that jewelry, and Mai is unadorned. It's very interesting--I can compare them to Inu-Yasha and Sesshoumaru--except these two aren't trying to kill eachother. ::grins::
