Use the pen tool and try to find all the dark spots on his face.
Then just fill all the selections black?

or you could try that :http://www.spoono.com/photoshop/tutorials/tutorial.php?id=46
notice the signature?

that is excelente, Mr Lazyroll, did a treat
you can see my effort above, i now have a better angle source

If your interested, this is a birthday present.
my friend has a Che Guevara tshirt, and we wind him up calling it charles manson.
his name is Gazzard, so im printing a tshirt with a picture on it, and the words "Che Gazzarda"
