With the "face" about done, it was time to reveal the inside of the cyborg head. Using the same path with which I made a selection for the face, I made a layer and filled the selection with a color. Any color is fine, because you won't see it later on. Above this layer I copied the "head hardware" image into a new layer. Holding the alt-button with my cursor between these layer I connected them and made the bottom-layer into a mask (image 9). This way I could easily move, rotate and resize the image within the mask. However, if the image in the layer above it becomes smaller than the mask, you will see the mask itself.After resizing, rotating and moving the image of the head hardware, I added some shadows with the burn tool for depth, with the "face" as a guide (image 10).To reveal the thickness of the rubbery "cyborg-flesh", I made a few paths (image 11). After making a selection with the face path, I intersected them from that selection. I filled this with a dark red-brown and used the dodge and burn tools to add depth (image 12).In image 12 you can see the lock of hair had to be placed over the mechanical inside. I copied that part of the hair into a new layer and masked it clear (image 13). Then I duplicated the original image of Catherine and highlighted and darkened the edges of the head here and there, as well as added some shadows (image 14).
