update

1_for the section, I prefer the one on black paper, but I think it should be more a proper light section. So, the sky (you background color) is not pure black paper but a grey (kind like a sky during the day but in a greyscale version), then the inside church should be more contrasted. It is black on the lower level and you have the all the light effects at higher level (like you have now but more contrast). Basically a more real space-light and less texture-light with more contrast. And the sectioned wall should not have the same colour of dark spaces. Maybe all the sectioned lines and architecture lines are white (so the sectioned wall is infill white) and the light is more gold colours.
2_Priest image is good, again I will make the foreground darker and the one near the altar lighter, now the light in your space is not affecting much the scene with the priests.
3_top vire is good, almost nothing to change, or maybe give some gold aura to the ground of the church, maybe on the entrance direction so it doesnt seat as object on brownish-cairoish ground. It looks almost your church is sitting on the top of other buildings.
beside those little points, they are all good.
