Here is an example that illustrates two concepts in composition. First concept is picture within the picture. Sometimes a perfectly good image includes another good image within it.
Second is refinement; studying what you are looking at and understanding what exactly is igniting your creative fuse. In this case it was the light on the hull. Through a series of images that gradually excluded non-essential elements, I arrived at the second photo shown below, which is entirely about (1) light and (2) texture.
