I started out with a photo
and Gimp'd it into a black and white version with colored eyes. The eyes actually got a subtle anime treatment and are scaled up to oversize.
I've been interested in the 3D high texture things I'd been trying. So I underpainted this by painting all the white onto the canvas in very high relief modeling paste (marble clay and acrylic binder.) Painting over this was easy.
I painted everything a flat Mars Black and then Titanium White onto the raised parts. I painted some color in the eyes to emphasize the stare.
This painting is 24"x30" acrylic on canvas.
