Swoon

I've always been amazed by Swoon's work.  These are insanely beautiful and intricate illustrations and prints, and installed in an urban environment, they just take on a whole new light.  I love this one in particular because of the yellow tone on and already unique turquoise wall, with those great splashes of color throughout.  I love the style of the portraiture and I definitely see it come through in my own work in some ways.
