I created this Asset by following a tutorial by GET Tutorials: https://www.youtube.com/watch?v=HiCR-f6i2nQ.
I created the composition by following part of a tutorial by Blender tutorial: https://www.youtube.com/watch?v=E1NubPTRUQs.
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.
