BA3: CS: colour studie

Here is my drawing of my final image for my character who is meant to be the hop-o but with an old-fashion style robot look.From my search of looking into robotic designs from looking at the muscle construction of a robot it is often displayed as Pistons than organic creatures which have muscle I wanted to join this to the hop-o as the hop-o and the book is described as a robot but I also wanted to make this look old by making these Pistons within its certain body parts looking as if they were wooden.
