Greetings @AskaArthorZ !
You’ve been a lighting artist for quite some time! What sparked your interest in lighting? Is your lighting art solely expressed digitally or do you also do real world lighting?
I believe adding the volumetric fog to a scene such as this was a splendid idea! I gives it that factory feel of steam, gas, chemicals, and smog while also giving you the intended layering effect. Wishing you the best of luck in all your endeavors!
