You ever saw the art of rebuilding a face from an ancient mummy that archaeologists found? Now it's your turn to do the same! Here under is a list of skulls provided by www.sxc.hu. Your goal is to pick at least one of the skulls and rebuild the face from the same angle. You may rotate and proportionally scale the skull image, but you're not allowed to alter it in any other way. The reconstruction has to be done with several face images, you can not use only one face photo for it. Neither can you build the face completely in 3D nor can you completely draw it (however, you can draw details if needed). If you want, you can add more than just the face (body, background), that's up to you. As long as the face looks as realistic and exactly according to the skull as possible.
The skulls:
Skull 1, thank you nighty77
Skull 2, thank you rkiser
Skull 3, thank you eugene w
Skull 4, thank you groesel
Skull 5, thank you Sarej
Skull 6, thank you ericodias
Remember, you have to start out with one of those, you can't use your own skull source.
Good luck!
Edit: please show the skull superimposed over the face transparently in a Step By Step.
