It fits with the rest of the art, not like there's a highly-detailed vagina surrounded by vaguely-detailed image. Believe it or not, there ARE some girls who don't wear panties/bloomers/lower undergarments.
I generally love the no_panties pics, but in this case I agree. It's incongruous with the striking landscape, lighting, and so on. Two great tastes that don't taste great together here.
