In these three pictures below are elements of simplicity, lines, and angle:
Lines is shown in this picture by the combination of diagonal and curved lines. Linear elements that are photographed diagonally are seen as more dynamic than those placed horizontally. The lines also show the depth of the valley due to the way the curve vertically.
The picture below is an example of simplicity, it basically means something so simple can be the main object due to the neutral background.
Picture below is an example of angle, the picture is taking at the feet to make the feet seem bigger than all the other objects in the photo, such as, the couch. Using different angles can make something look different in size, shape, or form.
