Hello. You did not inform the subject of your research, which makes it difficult for your question to be answered accurately. However, I will try to help you in the best possible way.
One of the most important points in the presentation of a research is the elements that will compose the presentation (by slides, or other media) with little text and present more images, graphics and tables that make the presentation more dynamic, attractive and do not tire the audience. In this case, we can say that the assembly of the Slides is the most important point to consider, because the success of the presentation is directly related to this.
