Ok, this is a rough skin, more of an idea/outline (ie: yes I know it looks cut and pasted).

I made the whole thing in UPaint to formulate ideas.

I want some suggestions on what to do with the arms and legs.

I thought I would cover the lower arms (forearms) with the carbon fiber like in the upper 'radiators', and cover the thighs with the same paint scheme with maybe some gauges (oil pressure, tach...etc.) and then the lower legs with the same carbon fiber.....

Your thoughts?
