Try this in place of your slide 18.

If you have an image that conveys some of the point, you can reduce bullets to key words.

When you talk you will explain those three key words. You won't be reading your slide, and the audience will be listening to you.

The image will make connections for comprehension and retention.

Something like this could be the background to what you say about concrete stories, illustrations, etc., around slide 24.

The picture does some of your work. It uses the architectural metaphor and serves as a mnemonic to you as you speak. It might even catalyze new observations on the fly.

Here I'm playing with your architectural image -- not as something to include in your talk, but as a concept for you as a speaker.

Not many buildings have a dumbwaiter any more, but think of that as a metaphor for image-rich slides. They bring your concepts up, and set them before your audience.

The image does some of your heavy lifting -- and that frees you to just talk to your audience.

Using HaikuDeck this way allows you to have fewer slides, placed at the higher level of your outline.

That gives you much more flexibility -- you don't run out of time with ten slides left to show.

The audience can stay with the outline and not be distracted by too-frequent changes
