1-lighting is harsh. looks like on-cam flash to me given the shadow. I'm not sure what I'm supposed to do with this one. Is it a funny photo ? or an odd moment.
2-good
3-good-would be nice without the officiant, but there's just not much we can do here. I got a tip last wedding from the officiant who said that I should ask officiants if they wouldn't mind moving for the kiss shot. She suggested most would like the idea.
4-crop above photographer in the frame. Meta shots are cool to include, but perhaps not when it emphasizes the emptiness of the church and their wedding.
5-I can't swear by this, but it looks to me like a flash + ambient shot in which the ambient (tungsten) portion was blowing out a little. Ease off on the exposure and go cooler with the color balance--or go B+W.
6-Are you the main photographer ? Even if you aren't the guests seem to be looking at you, suggesting that this was set up in some way. Why not spend 2 minutes moving people (or asking them to move) to avoid completely preventable decapitation problems as that which occurs in the upper right of the photo ? Take care not to be so passive.
7-I would like more depth of field.
8-oddly cropped / framed, judging by the space on the right 1/4 of the image.
