Vipers are reptilian humanoid females from XCOM 2 game. I was thinking about making it to cosplay but there are problems with their anatomy compared to mine (human). You can look at their anatomy on concept art or game model. So I decided to make it robot instead. So the head would be able to look around and possibly move her arms but I will probably not do lower half of her (at least not with snake-like movement). At first, I want to make it bust (head) only and see how it goes.
