The way you've brought out the detail in the church's walls when in contrast to the harsh light within and the dead of night is nothing less than masterful. Very little over or under exposure and the blue hues are fantastic in the rest of the image. That said thought I feel as though some of these blues are a little over saturated, but it does give an extra 'oompf' to it's over all Impact.
The small piece of building on the bottom left of frame balances the colours out rather nicely.
This is a really nice image, full of fantastic story telling.
