I am only joking about it being a painting, but that is how it looks on mine. The different shades of blue in the sky and shades of grey in the shadows are all separated by lines, like brush strokes, instead of being smooth. It could be exagerrated a lot more on my computer, I dont know much about my settings. But like I said it is a nice picture/painting, whatever.
