Awe. Some.
Basically, Banshee's a Shadow Mew.
So, the body is like, the shadow-ey purple. And super-skinny. She's got a few stray fur-hairs on top of her heard, inside of ear is silver. Eyes are like.. Well, XD001's. o3o
She's got chained collars around her neck and tail, both covered in heiroglyphic-ey designs (You can totally make these up; lol). The collar has three actual chain... things, and the tail has four.
I *think* that's it.
If you've got questions on the design let me know. :3
