#6 very good. would like to see it inverted, so single ring is at top. Cream color needs to be lighter, more of an off white with a butter tone. Very nice.
Getting better and closer. The adjustments now are can the top purple ring either just touch or just slightly hover above the gold and red. The cream and silver colors are too similar. The cream must be lighter, perhaps slight butter yellow color. I am also imagining none of the background and it all standing alone without the bluish background and shadowing. Still hoping for a bit more 3D shading of the rings.
