Look at the images on the PowerPoint. Think about how these pictures have been constructued Collect images of faces. Cut out parts of faces from different pictures. Choose different parts of the pictures to create your own face collage. It doesn't matter if the facial parts are different sizes or shades of colour. They don't even need to be the right way round or in the correct place on the face. Move the different parts around to decide where you like them most, then stick them down.
