This is a work in progress and i' am going to be working on it further.
First i found an image of a train driver and then cut him out and stuck him on card. Very basic.
Next i thought about how i could focus on just the head of the train driver. So i came up with, making it 3D. I done this by using a slightly larger head and placing it on top of the body. Extending the sides so it could stand out.
