Here we were given the task of creating an image by drawing a scribble on a block colour with the lasso tool changing the colour of the shape with the hue saturation settings. My scribble reminded me of some kind of sea creature, so I ran with that idea. I added more lines to show what I could see in the shape.
I carried on adding more and more shapes to experiment with the image. Although they are not perfect images, it is a great technique to use for idea generation.
