Lines and Shapes That Merge

What struck me about this image were the lines that all lead to the center of the composition. They merge together, streaming down from the top, the sides, and the bottom. From the two sides, lines lead to the center. From the bottom edge of the frame, the eye is led upward by the green shrub, which itself is a triangular shape, the apex of which again leads the eye to the center. You could almost say that the whole composition consists of several triangles, all having their apexes at the center. In art, triangles are often desirable shapes to have, since they quite often create interest and tension in the image. The image therefore is composed of repeating lines and shapes, another desirable quality, while the red-green contrast between the shrub and the rocks is an element that creates color vibration.
