Photography contest suggestion: Selective focus

Selective focus is a technique that can be used to make specific objects stand out in a photograph. Focus on the specific part of a subject you want to highlight or emphasize, and “ignore” the rest, letting it fall into the blur of the background or the foreground. Selective focus is often used for subject studies, to draw attention to a subject or part of a subject and evoke a meditative or contemplative mood when viewing the subject in context of its blurred but recognizable surroundings.
A telephoto lens and a wide aperture size (or f/stop) can help achieve this technique.
