Nice, Chris. Has a very serene look to it. Maybe letting through a bit more of the highlights would liven this up a bit. Looks a little flat as is. (the lighting, I mean)
It is a beautiful stained glass window, Chris. Unfortunately the large expanse of Black overpowers it and makes it look washed out.
You might consider eliminating all the black except for about 1/4 inch.
I tried that, revived the colour a bit and it really stands out.
All the figures are more distinct. Especially from the center panel and upwards.
