Floating Virtual Singers

I saw a creative video animation today and decided to recreate it in DaVinci Resolve. This is the final result using stock video footage and music. It’s pretty close, but I need to figure out how to add drop shadows (or a dark outer glow) to the floating videos. This could be used for one of those virtual choir videos where all of the beautiful singers go floating along in an interesting pattern. The stock video footage is courtesy of Pexels and the music track is “Escape” by Eveningland from the YouTube Audio Library.
