Compositional photoshop exercise

For my compositional photo I chose Canadian actor/writer Paul Gross. For changing the background, first I created a new layer, background copy, and then I used the magnetic lasso tool to outline the figure, and after I outlined I copied it, and then got a new background, and then I pasted it into a different background. After I did that, the figure was too big for the background picture, so I scaled it down to fit. I chose the desert background for Paul Gross was because I figured he wouldn’t be in that particular place.
