I spent quite a bit of time with the skin and have gone through a few rounds of painting! I'll let the photos do the talking. The arms are actually magnetized so I can swap out with the other weapon options. Those options I have not painted and will paint them when I need to use them - mainly because the Carnifex is going to proxy for my Tervigons until the actual model comes out. At the moment, I would not use the actual Carnifex in my games as the Trygon is a much better Heavy Support choice.
