I found these at Deviant Art - this pencil artist is simply amazing. He's done Vash, Legato and Wolfwood in a realistic style, in pencil - the coloring was done in PhotoShop. These are so detailed, they almost look like photographs. I thought I should be able to feel the wrinkles in Wolfwood's jacket (although he looks much younger than I would have imagined him). Even if you're not a Trigun fan, have a look. Go comment and tell him what wonderful work he's doing.
