Graphics Tablet? I was thinking old ball tracking mouse!:ROFLMAO:I'm not sure that's Photoshop talent per se, but portrait artist talent ... with a graphics tablet, and a photo to trace for the initial sketch / outline. Switching colors and brushes in Photoshop is as easy as doing it from tubes of pigment and a jar full of brushes. Knowing brush strokes is tougher, but many coming out of art college can do it fairly easily ... especially if both hands are out-of-frame :^)
But definitely cool, when speeded up.
