Underwater

What i did for this picture is a put the ocean picture on a transparent layer, and shrunk it using the scale tool. Then I opened up another layer and edited the diver, then scaled it. I opened up a third layer and pasted my head on it. I zoomed in and erased around my head to get rid of the sky in the background. I use the color picker tool to select my skin color, and airbrushed the arms and the legs of the diver. Once I had shrunk my head to the size of the diver, I merged the layers. Then I scaled the diver until it became the correct size for the ocean and I merged the layer with the background.
