I started by tracing the arm from my bitmap and then I shading it in according to my vector.

I then traced my body, shoes and mask and also shaded them accordingly.

I added colour to the coat and buttons.

I traced the legs and then added detail using the pen tool and then added shade.

Using the sketch I drew earlier I created my robotic arm and shaded it.

I then created my robotic hand also using my sketch and then added it to my arm

I Then put it all together to get my final piece.
