Thanks guys! You are right about the Ripley fig, it's way off! I was thinking of resculpting here at one point. This'll be the first human fig I will attempt to paint so if I don't like it in the future I can always try to sculpt a new one and replace her since the cage bars will not be glued permanantly.
I have also thought about the hoses. First they are too shiny for my liking, a little too thick (not much) and I will definitely fabricate some sort of simple pneumatic couplers where the hoses connect.
I've already started painting the main parts, I'll post updates soon. Thanks again!
