To provide an accurate answer, I would need to know which artist or artwork you are referring to, as different artists use various elements of art to achieve emphasis and balance. Common elements used to create these effects include color, line, shape, texture, form, space, and value.
For example, an artist might use contrasting colors to create emphasis on a specific part of their composition, while balance might be achieved through symmetrical or asymmetrical arrangements of shapes and forms. If you could specify the artist or artwork, I’d be happy to help analyze the elements they use!
