The female model's figure, face, and clothing have been changed, as has the angle of her head (to accommodate the new face). That wasn't all that easy, but I enjoy a challenge. The price tag has been removed from the spear. Nothing has been done to the male figure other than lightening the shadows.

The photos were deliberately shot in the light and shade of trees so the figures would better match a jungle background. When you plan your composite photos in advance like this, you can get some pretty awesome results.
This was originally done as a study for a painting, but I'm not that good a painter. Though I do know I'm a hell of a photographer and photo editor.
