This place had some really awesome angles in the architecture! The camera was held completely horizontal, even though the wing in the background looks slanted, its actually that grand staircase that is.
I would think that the slant of the staircase windows and structure might be made more evident if the picture was taken with the straight elements of the rest of the building (the part on the left of the photo) at the horizontal. Does that make sense? In other words, essentially rotate the photo counter clockwise about ~25 degrees. Of course, then the statues wouldn't be square. Tough shot I suppose.
Clarity and color are excellent. Biltmore is truly a beautiful place to have a camera.
Oh, and chateaux is plural, I believe. Of course my French class ended 20 years ago....
