I'd crop half the Black from the top and 1/3rd from the left side to provide better balance for the rings and increase impact.
A centered subject will almost always lose impact and viewer concentration as one's eyes will always be diverting to one side, then the other, no matter how intriguing the subject material.
The lighting is a bit hot , particularly on the front ring, and less intensity would have shown more of the fine detail in the central band.
Titus 3:5-7, "Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
6: Which he shed on us abundantly through Jesus Christ our Saviour;
7: That being justified by his grace, we should be made heirs according to the hope of eternal life."
Why did Jesus Christ have to die on the cross if all it took was good works to get to heaven? It is THROUGH Jesus Christ's blood that He saved us from Hell. If we could get to heaven on our own then Jesus Christ would've had to die again and again.
If you ANY questions please pm me.
