Skull face experiment

For this experiment I used photoshop to merge a portrait and a skull;
I used a mask on Photoshop to hide and show parts of the skull through the face.
I really enjoyed doing this experiment even though it was tricky to get the hang of, once I knew what I was doing I thoroughly enjoyed it. I would like to do more of these images as I really like the final outcome and am very pleased with it. This experiment could have been made better if maybe I made a series of them.
My inspiration for this experiment was Carsten Witte, here is a collection of his photographs;
