The artist of this is Dan dos Santos.  I chose this because it is very legible and highly detailed even though everything is just grey and black. It has a lot going on in the picture but everything is pleasantly readable. This piece uses Black to separate the man on a horse from the background image.  Everything else is a light shade of grey which allows your eye to see every detail and tell each object apart from each other, still keeping the main focus on the man and horse.
