I'm not sure if you want a critique on only the conversion, or all aspects. So here goes on whatever I see.
#1 & #2 camera angle is too high. You missed one of the bridesmaids. Tonal range in #1 is not so good, as the men's pants blend in with the dark background. Overall not a flattering pose/angle for the women, but a better tonal range.
#3 no comment
#4 Main participants are not captured very well due to the extreme long shot. Way too much foreground with all those dark chairs. Main participants are not in focus, but the chairs are.
