I've decided to make a two arm version first so that later I can use it as such. Then I'll add on the other two arms in a different file for this comp. I found a couple of wires for the back but I think the mesh flow is only so so.

Here's an update. I've been working on the body for about 10 hours (minus several hours web surfing) and I still have quite a bit left to do. Man this is a slow process.
