Here was a basic preview of what it would look like. I was worried you couldn’t see the spots…. But then I added colour.
Here was the background effect in colour.
Then by computer I added the drawing of the giraffes to complete the effect. I don’t know how to manually transfer the image onto the background, so in real life all I have is the background image, plus the plain outline drawing. If anyone knows of a way to transfer them together manually, not just on the computer, that would be ace!
