Juan Francisco Casas Ruiz drew this out. (his name is red because I just copied and pasted) The fact that this is ball point pen blows me away. It really makes me feel like I'm a long way from my peak when it comes to skill level. More of his work is here: http://www.juanfranciscocasas.com/galeria.aspx?idm=en
All of his drawings come from his own photography of his friends on their more ridiculous nights. I would be even more impressed if these were all from sittings but that would also be ridiculous. If you check out his site his paintings are just as realistic. It reminds me of the photoshop painting that we looked at at the beginning of the semester for the horror movie poster except this is all done by hand.
