Some quick concepts for a female sci-fi/robot/whatever character. I will continue drawing some until I find something interesting and refine it.
I have drawn helmets and bodies separately to be a bit more free about the shapes, mix them in the end and have more ideas.
So far my favourite helmets would be 9, 10 and 18.
My favourite body armors woud be... 10, 11, 16 and 17, I guess.
