Hey Daniel!Keeping presentations interesting and engaging is so important, in my opinion, regardless of your role.
Personally, I get engaged with presentations when the presenter is well prepared and enthusiastically deliver the pitch. Having well organized slides is also key I believe. Trying not to crowd them with too much information is one way to achieve that, or if you necessarily need to show a lot of information, at least show them in parts. The time length of the presentation should also be according to the type of event, crowd and topic. I like to look for the audience body language for signs of interest or boredom and adjust the delivery based on that.
Interesting input from anyone else and feel free to comment or add anything else!Salvador
