@swikni Really cool to see you try so many different setups! Your experiments were all over the place, in a good way; from moderate to wacky color schemes. I really like to see that level of exploration.
These are my faves:

The Eevee ones are pretty noticeable. It definitely takes more effort to get them on a comparable level to Cycles. One thing to look out for is too much blow out in the highlights. It can be too bright for taste. The 3rd from the left in that row (green/purple/pink) gets a little too blown out imo.
Overall an A+ for me in quality and effort.
With your light match I think you’re quite close but difference in the model’s detail level is a quick disconnect. Yours is also perhaps a little too blown out by comparison, though that could be due to details too. While the source is definitely blown out in the highlights, the blowout isn’t quite so broad. It’s B+ from me 👍
