Portrait of an artist's daughter....

I've started a new painting... a portrait of the kid. It'll be 16x20 and I am doing it in acrylic (yeah, acrylic). I started the underpainting (below) this weekend, using Liquitex Basics in raw and burnt sienna, and Windsor and Newton Galeria's Titanium White (so, translation: these company's cheapest grade paints) very thinly, very much like watercolor.... We'll see how it goes.
