Colored face

The picture is kinda old, but it's the last picture I coloured. I could submit all my sketches, but according to the directories available, they should be all into the scrap directory. So, that's the same person as the one here: [link]
While trying to post a link to the picture I accidentaly faved it and now I don't know how to unfave it. How can I post a link to the picture that shouw a thumbnail of the pic itself?
