I toughed I take out few details this character has before the final product cuz most of em is not very well seen when shaded and lighted.
Okay the mark on the right is well know by now I hope. The other are part of the her hand. In short her hand is very useful device for controling stuff which can be controlled by some kind of movement tracing mechanism. Usualy we stuff like this on the hand as a glove. But gloves can be damaged or taken of, or just simple lost. And they are costy to replace. But usually we don't lose or take of our hand so it much more realibe and easier, and cheaper to build in everything on the hand.

Well anyway I could talk about the mark that why they are like what they are, but I guess no one is interested. Enjoy.
