I created the composite in Pixelmator, and toned it with the Vintage Iris effect.
While I was at it, I made a comic version using the Paintoscope filter in Comic Life 3. I like the Paintoscope filter a lot, and am considering using it for a comic project.
I made the composite from three different photos.
When I took this shot, I had the finished picture in mind. I did not know exactly what it would look like, but the general idea was clear.
I did a bit of cut and paste to take the foreground and extend it into a background plain.
It is a selfie. I put my camera in a tree, and used the 10 second timer to delay the shot.
Unfortunately, part of my shadow is blocked from view by a car, so I did a little bit of repair work on the shadow for the final picture.
