PowerPoint on suggested website UI changes

I will provide 9 landing pages and I want to make observations that support suggestions for UI improvements. These improvements mostly relate to the layout of the page, the location of links, how prominent navigating around from parent to child pages are. I want to talk about how I see things from a customer experience standpoint. My recommendations on how to fix any presented challenges will help improve the customer experience on the website. I need a PowerPoint that captures all of these observations and suggestions, with concise actionable steps. The slides will be super high level with more detail in the notes .
