What is the style of your next presentation? Will it be cheerful, energizing, serious, professional, motivational, sad, optimistic, modern, classic, old, inspiring, dramatic, etc.? Or a combination of this?
Define what the style needs to be of your presentation as this will dictate a lot, for example the style of the invite of your presentation, the style of the supporting materials (including the presentation materials such as the slides), the pictures to be used (if any), the words to use, etc.
Carefully select the style of your presentation to match what you want to accomplish with your presentation.
