There's always this one that was on the Toy Karma II site. I would imagine that geotaro's picture is more true to color.
Actually, mine may look a little different because it was taken outside with very bright but overcast skies - under very different lighting than Kirby's photo...
I love the small details sculpted into Yamomark toys, e.g., the Barabaran ladybug and the snail on this guy. Sculpting really seems to be his forte.
