I posted a similar query in Lighting thinking that it is a lighting issue. But it turns out that I need to fix a lot at the material level before I think about lighting.
I am trying to recreate this image from 2008 in Blender
I got somewhere close but lot more to achieve. My efforts so far
These look nice in dark background. But in white background of file manager, Eevee outputs look very dark. Last 2 images are Eevee. I am using 2.82.
It would be nice to get as close as possible to the source file. Thanks.
