Spacing: Create a sense of movement by adding active space (the area your subject is facing) and eliminating dead space (the area behind your subject).
Yami is the main focus in the photo. The only two subjects are Yami and the grass as the background. This eliminates dead space and distracting factors.
Leading Lines: Use architectural lines - walls, fences, roads, or any lines to lead the eye through the photograph and draw attention toward the main subject.
Yami is the main focus. The background is the leading lines, which in this case, is the wall with a line pattern. The exposure is a bit low. There is no depth of field.
