This image is a double exposure of a self portrait and nature image that I took, the post processing was done in Photoshop where the portrait was made into black and white and prepared for the overlay of the second image, using lighting tools and layering settings, they were merged together and the first portait was moved slightly to the side to not be overshadowed.
The idea is very nice, but for me it lacks in execution. I would have removed the lines over her eyes.
