How to shoot in space

I think space can be expressed by the distance between points and lines.

For example, the patio has a sky surrounded by four lines in the middle, surrounded by dark stone and wood structures, forming a space.

For example, trees, the horizontal branches and vertical branches above the picture and the roots below enclose a space.

For example, in a room, simple lines between white walls enclose a space, and a brightly colored object in the distance can better reflect the sense of depth.

The space is not necessarily large. Maybe a small gap in the grass can feed a nest of insects. This is a space.

This is my understanding, let's see if it inspires you.
