Well, I didn't comment when you posted the first eight, but here goes now ...
I remember taking exactly the same shoes shot at one of my first weddings, and mine didn't work any better than yours has. You've taken a photographer's picture. The one that brides want is a nice pack shot of their wedding shoes, preferably in context. Not something "creative", unless it still shows the shoes to good advantage.
The second is very close to being a cracker. Your timing was obviously out, but I reckon you could to some extent salvage it by cropping tighter on the bride.
Third one would have been great if they were all facing you. As it stands, it's a photographer's picture.
Well seen, well caught, but not obvious to anybody else what's going on, so not one for your portfolio if you want more weddings.
Snogging in the punt is too obscure for anybody but the couple themselves. Either you didn't see it in time, or you were trying too hard.
The one with the champagne bottle's well caught, but I'd bin the other two punting shots. Compared to what else you got, they're Uncle Bob's snaps.
The remainder are at worst very competently done. Some of them are bloody excellent.
Ignoring the first eight you put up, I can't see a single thing about any of them which indicates to me that there's anything in particular that you need to work on. In fact the only real nits I can pick are ...
Pub dining sign - you needed to lean right a bit to get more separation between his head and that clutter behind/above it
Crossing the road - it's only just there as a picture. I reckon it'd be stronger with a tighter crop.
Hug in middle of road - I'd lighten them a bit to get better separation between his face in particular and the background. They're tending to merge into it, probably because of the treatment you've given it.
Heads on the bridge - is a near miss AFAIC. It's very close to working but you really needed to be further to your left to get just a bit more of them and the bouquet. (And yes, I do realise it's a grab shot)
Bridesmaid with her present - again, it's sooooooooooo close to being a good 'un, but we really needed to see just a bit more face (and yes, I have been there, taken the same picture and kicked myself later - many times ...)
And that's about it, except to say that the effects are a bit over-done for many normal people's (ie potential customers') taste, but the straight processing's fine
If this really is a first wedding, it's exceptionally good, and IMO you'd be daft not to do some more. But if you do, ffs don't go studying other wedding snappers' pictures much more. You're seeing the pictures just fine as it is, and some of the ones you're seeing are ones that a lot of wedding snappers wouldn't - mainly because it's all new to you and you're going into it with your eyes wide open.
Nice one mister.
