Well, Zero's shoulder. It's sticking out a bit far from his body, at least taking its location and positioning into consideration. Ciel's hand, the one furthest from us, is also positioned in a slightly awkward way because of how her arm is positioned. Mostly because it's hard for most wrists to do that sort of movement. Let me try to explain a bit better because I think I'm not being too specific @-@ Her wrist/arm is facing downwards with some tilting to our left, but her hand is facing left without the same tilt down as her arm, so it makes it look awkward, in a way.
I think that's around it o.o But still, excellent work.
