After creating a Robert Pattinson doll, I've had numerous requests to create a Kristen Stewart doll - not as Bella Swan but as herself, the celebrity.
The doll used is a 15 1/2 inch Bella doll by Robert Tonner. Full facial repaint and shading as well as extensive hair style make over to replicate the features of Kristen Stewart, particularly as she appeared in a recent publicity shot. (Please see auction link above to view pic of the reference photo used.)
The inset photo on the bottom right shows the mass produced version of the doll used as it was originally released.
Repaint is a new form of pop art, wherein the doll's face is treated like a three dimensional canvas, with the added challenge of painting within a very small area and an even greater challenge of recreating a real person's likeness. Since dolls are basically miniature pieces, brush strokes and shading have to be very controlled and precise.
-- acrylic paint and ultra fine brushes

Must take lots of patience and time to be this good.
Also I wish I had a custom doll of my OC < . < but I imagine that would cost a ton, and I don't even know where I could find that.
