For this exercise we were given a line drawing in Photoshop and instructed to colour and shade it so that the line drawing was made obsolete. The original line drawing has roughly the same shape but I made a few tweaks of my own, for instance removing a few body parts or adding some. I was also experimenting with creating texture using lighting and shading instead of colour. The result wasn't as good as painting a texture on the character but it's a start.
