This is a scene I finished a Long time back that includes probably the best work I have done, or at least my proudest render. It isn’t entirely complicated however the lighting, bokeh, and soft glow is like msg for my eyes…
However, I have to admit I didn’t save the scene and I have no clue what my compositor setting or color management was 
and I didn’t save the custom texture I used for the hdri ( basically the projected texture of a hand-painted sphere with the colors I picked for the lighting. In my opinion, the lighting set it apart and I’ve never come close to topping it although I managed to recover the objects so I have tried to recreate the render (to no avail) multiple times spicing it up in different way’s but it just isn’t the same.
(blenderartists.org won’t let me put multiple images because I’m a new user… so y’all will have to just believe that they new renders are subpar to the original my magnum opus)
