This is Kergan again. He's an role playing character from the 'The Black Eye' (or DSA, as it's called in Germany).
The sketch of this picture can be found on this gallery, too.
The sketch was transfered on tracing paper (using a 0.5 mm gel pen), then copied (without the hair), then hair and shadows were added using a mechanical pencil (0.5 mm, B)
Despite looking a little bit more serious than intended, and the blind eye looking too flat, I think it's ok for my first portrait...
