Light

Hard light. This photo is compositionally creative and captures an important moment. The details included in the frame all need to be there.

Soft light. Is fluorescent light soft or hard light? Regardless this photo is important. Hospitals are depresssing, cancer is more depressing. But the photographer playfully captures a moment that emphasizes love.

Diffused Light. The subject is a sillouette but enough detail is preserved for the viewer to get a sense of the subject's exhaustion. Follows rule of thirds. I don't like the tree on the left.
