Winter brings amazing sunsets. Clear skies also bring cold days, like the -10 C below outside as I write this :-)
This is an other shot from the rampant of Akershus Fortress in Oslo.
The composition rule called "Rule of thirds" is about drawing two vertical lines and two horisontal lines across the image, making 9 equal rectangles. According to this rule you would typically have the dark foreground here covering 1/3 of the height of the image. The people would be placed in the left intersection, and the tree in the right intersection.
In some images this rule is broken on purpose, and show only a small foreground like the black area in the image above. If there is enough detail in the sky it makes up for the "mistake".
Here of course you could argue that along with the dark area of the sky it actually covers a third of the height anyway. :-)
