I did one a while back for the P4 Guy. There is an animation of the hood raising and lowereing here. I like the way you have sectioned the materials to aid mapping, its something I did not think of when I did mine. I just went for a plain front/rear planear map. Regarding jointing, I think I just kept the same as the figure with a little lengthening of the twist at the neck and it all worked out OK. You have a good model there, :) Regards
