Find 2-sets of collection with photos for a landing page

I need someone to look and find a collection of photos that work together and fit together for a landing template. I will provide the current version of the page with photos where you will see the samples. All I need you to go on sites like Unsplash, Pexels, etc and find high-quality free photos to so they will fit the theme I will provide.

I will provide you with 2 topics each will require 12-15 pictures.
