Look Up Doodles - Lighting Studies UE5

Hey everyone !
This project was an attempt to get better at lighting.
While creating a bunch of scenarios, I learned more about physical lighting and the science behind it.
I created a bunch of documentation and data for myself to use. Tell me if you would like a blog post about that.

Renders 1-4 are real life realistic scenarios.
Renders 5-7 are moody and stylized.
All the rest are variants from the 7 first ones.

There's a little living being in all those images, can you find it ? (spoiler at the end)
