I love these oil paintings by Lara Viana. Even though I'm missing half the detail by viewing it online I can still see how thick the canvas is with impasto. How much of the painting is carved and squirted arounded. It retains a high level of dimension and 'reality' even though its' brushwork is so large and unarticulated. Last night I watched Simon Schama's the Power of Art: Rembrandt and they mentioned Rembrandts deft ability to utilize rough brushwork to actually be more dimensional and closer to perception than any superfine articulation. I believe Viana's work accomplishes this as well.
More work here.
