Cinematic Sci-Fi Scene-Blender Practise

I created this Asset by following a tutorial by GET Tutorials: https://www.youtube.com/watch?v=iHOwExuK4ow.
The shader in the tutorial required an image file, but I could not access the file. So, I substituted the shader with another by NAM3D: https://www.youtube.com/watch?v=L-23Jzu6Hd0.
I created the Vignette effect by following a tutorial by Ryan King Art: https://www.youtube.com/watch?v=0RyaSB9qyL8.
I am currently using Blender 4.2, so I used a tutorial by Ryan King Art to recreate the Bloom effect for the Asset since it has been replaced with Ray-Tracing: https://www.youtube.com/watch?v=OhU-GV1CAF4.
