Aye, I think that whiter volumetrics and MUCH thicker density would be in order here... It took me a few re-looks just to even notice them, and it's such an enchanting effect you might as well overdo it a bit. You can always settle for a happy medium later... Still, back to the topic : Perhaps it's your volume quality settings? Are you using multiple spotlights, or just one? Are you using a spotlight with a radial in front of it? Just some ideas....! I agree with Analog about the gold material, way too shiny for gold. More mercurial, with an orange tint? Also, I'm not sure about the WHITE parts of the scene. What is making them so bright? I see some candles in the scene, why not use THOSE to light the scene, alongside the volumetrics? It would be much more accurate... Give it a shot! (try the lights on squared falloff for the best results, just crank up their magnitude a bunch...)
