Well, I think colour adds more to the intrique and mysterious appearance of the subject. And I think you captured colour really well. Bring it back! :-)
I was going for a light and dark processing of the background to differentiate the two sides. The color version with a slightly tighter crop is here . Should I change it back?
I saw your original image here, in colour. I could almost see the blazing fire embracing those sinners up there ;-)
Why have you decided to go for greyscale version?
