Here are five questions to ask to determine whether your slides need improvement.

Contrast

Contrast helps focus attention, create drama and set hierarchy.
Is the prioritization clear, or is it indistinct?

Whitespace

Whitespace gives the feeling of luxury, drives focus and is like the oxygen of a slide.
Is the space open, or cluttered?

Hierarchy

Good hierarchy treats things visually according to their importance.
Is a parent/child relationship apparent or absent?

Unity

Unity is achieved through a consistent look and feel, image treatment and placement of elements.
Is the look structured or unstructured?

Flow

Flow directs the eye along certain, pre-determined paths to areas of focus .
Is there a clear path for the eye to follow or is that path unclear?
