Lots of color changes in the modern reproduction below, with added contrast that blurs many of the details. Although European landscapes of this period tend toward abstraction, they often retain a link with the natural world through the use of elements such as green trees and plants, blue sky, earth tones and so on. The reproduction seems to have ignored the painting's naturalistic qualities, altering the palette and also damaging the depth, energy flow, and emotion of the original. The image above is from Sotheby's, where the authentic work sold in 2014 for $2,045,000.
