Re-Lighting Subway Scene

Re-lighting practice of the City Subway Scene from Dekogon Studio on UE4.
I wanted to explore the idea of a subway train submerged in water.

Water shader slapped on a plane is from Karim Abou Shousha scene: https://www.artstation.com/artwork/9NDqvW
I did not wanted to use his UE5 Underwater Blueprint Tool, but deconstructing it helped me understand how underwater spaces feel. :)
