I've now added a texture, this is my first time creating textures. It's basically black with dark blue for the specular color and a muted red for the reflected color (not sure if the red makes a difference). One thing I can't figure out is how do I add noise? I can't seem to figure out which attribute I should attach a node of 2d noise to. Any suggestions? Like I said earlier I am new to textures, so any advice would be helpful. Thanks.

I also increased the size of the head and added a neckpiece. It's hard deciding if the head is the right size. In front on views it looks find but in this angled view it seems a little to big. Any thoughts on that?
