I liked the idea of utilizing a half body sewing mannequin to create something not quite standardized among monster types. A phantom like Banshee felt like a good direction to go.
This could be a fairly easy design to render too.
I'd would probably use a wire mesh for the head to give it the right shape but keep it hollow space. Some glowing lights inside for that jawa eye effect. For the cloak I'd like to utilize something thats reminiscent of human skin to up the creep factor.
The voice would be something I'd want to set up in such a way that the entire space is utilized for a 3D effect where it feels like its echoing from all over.
