try looking for tutorials on youtube
This Youtuber has some great showcases as well as tutorials, would recommend!
It’s important to understand the basics of lighting, so if you don’t know those, then I would recommend looking for a tutorial on that first.
I also recommend watching Speedbuilds, specifically focusing on what lighting settings they use. You will have to slow down the videos but It helps when you see the process.
(you seem to be trying to tackle quite a big project. Perhaps try taking baby steps?)
