..what makes 2 better than 1,3,
The snow-covered slope on the left has created a leading line down toward the creek.
The surface of the water is tinted with the color of the sunset.
The creek banks create another set of leading lines into the picture.
There is a dark tree trunk on the left and it is repeated on the right.
The mass of trees on the left balance the mass of the creek.
The combination of surfaces and textures (snow, then water, then trees, and finally sky) generate interest by alternating bands of color and texture from the bottom to the top.
(very subtle) the colors of the water (orangish) and the sky (bluish) are complementary.
The overall composition is very well balanced L-R, and top-to-bottom.
