First i found a picture of a shark on Google images and traced around the head and copied it. next I pasted as a new layer onto the diver pic and moved it off to the side. I then traced around with the freehand selection tool and copied it. I then moved the shark head to a position that I thought looked ok and then pasted the diver back onto the image and aligned him up with the image beneath.The leg of the diver overlapped a bit so I cloned around it to cover the overlapping parts.I used a tube image for the bubbles over the diver and then then created a new layer out of bubbles and copied that onto the current image as a new layer and lowered the opacity until I liked it.Next I selectivley erased around the divers face and the eye of the shark to bring them out more. I then created text and sized it to the postion over his sponge and merged all images. Oh and i also tried to burn the light reflection behind the shark but didnt do such a hot job at that one.
