I don't know what it is about working on paper, but the paint is really enjoying itself... It's like the materials have totally different personalities. The paper is receptive, forgiving, immediate. I spend way less time mixing paint on the surface; I just lay in the pigment quickly, so the brushstrokes end up being more visible and more alive, somehow.
I loved working on this brother-sister pair -- their eyes are so gorgeous and animated! Amazing how the paint, in its spontenaity, can capture the light in them.
