These are fine for a first wedding.
As far as critique, I'd say:
-that up-the-dress shot is a shot I would not have given back. I'd have been shooting in continuous mode and had a couple more shots to choose from
-framing could use help--it looks like you just weren't wide enough in that walking shot (feet cut off, heads at top of frame). Also notice in 1,4, extra bits sticking into the frame--clean up the images by making a slight crop.
-backgrounds are not-so-good in a couple of these (I see cars, graffiti). This could have been avoided by moving slightly.
