I know I'm really exploiting these three women on the beach - but I really like the photo - so here goes again.
The clouds were shot out of a plane and processed with Nik Efex and Fractalius.
The long things are reflections of palm trees in the side of a high rise in Phoenix. I elongated the image to fit the cloud photo.
Finally, the three women on the beach. Positioned that photo so they would not be obscured by the strange palms. Erased a bunch of the image around the edges.
