Great tones and detail seen on the light colored sheep. Try, try as I might and having stared at this a long time I cannot make a connection to something Halloween, sinster, or spooky. Now I did mention that the light colored sheep have great tones and detail but their 'seems' to be a black sheep in the mix but it gets lost/blends in the dark tones of the ground on either side of it. Perhaps the sacrifice is the black sheep....the black sheep of the family? Not sure.
