Tori textures would ruin it
Good that you decided to go away from gray - but you need more than one light source. Have one coming almost straight on and one from the left or right, both in different colors, do not make them strong or anything, just subtle light.

Also the light rays or volumetrics could use some cloud overlay variations and not be so clean. If it's clean it indicates that this has been there for a long time and the dust have settled.
