Looks like parking enfocement in my part of town. Looks really nice. Shadow catching in P6 has not worked at all for me, too contrasty and not enough coverage... I have used an old fashioned shadow catcher I saw in someone tutorial for how to composit images, she put scaled white ambient black refection box props whereever masses were in the image.. in this case, road and curb, this shadow can then be color manipulated in a layer over the main or background image in an image editor. It is a cool and surprising image.
