Here we go!
Processing
Try not to use PP that is personal to
your tastes. Tastes change over time, and can become outdated very quickly. A friend of mine who's also a pro wedding tog mentioned how he was shocked with his first set of weddings (after looking back at them) due to the styled processing he'd used. Many - many - people do this when starting out. It's a comfort thing: "I can make this better with processing". Dangerous, and usually the opposite is true. Have confidence with your shots. It's highly advisable to use WB balanced colour and normal B&W for wedding shots. The couple may not have the same processing tastes as you, but be too polite to say anything. Their tastes can change too. I've heard many stories where couples wish they didn't use at-the-time preferred effects in their album. Selective colour is one of those effects (*spit!*)
It's worth noting that soft contrast shots don't hold much impact in print - especially albums - people think they look misty or have had issues at print (seriously). People *generally* prefer punchier vibrant/contrasty images.
Posing
The couples are in the same pose in all the shots, and in each case, looking at you. Needs variety! Get them sitting down, walking, chatting, kissing, hugging etc. Frame them in windows, doorways, under trees, in bushes etc.
Always works to have them hold each other, face on - and have a kiss. Often they'll follow up the kiss with a giggle, which is a perfect moment to capture. Get shots of them engaging with each other, not the camera. They're engaged/married to each other, not you :¬)
It also works well having them look out of frame in some shots.
First image: the lady has her eyes closed/half closed. A lesson there -
always take 3+ shots of each pose. Nothing more annoying than having great shot which you can't use. Nice framing. There could be a little more subject padding on the left, which would balance the space upper right between tower and frame edge.
Second: shooting through things to give depth works great with things like flowers, windows and fences. The object in the front here detracts rather than adds as it's not consistent/close with the couple. Generally, use foreground objects that are linked with the subject. Stick them in a bush/tree and it's a perfect place to use blurred foregrounds. Monotone isn't the best processing technique to use with foreground blurring either, as the colours and tones help separate the elements of the photo.
Third: much better! Tells more of a story. If they were smiling at each other, it would be even better. When I pop out in front of people to take snaps, I often jest (with a smile), "Ignore me, I'm not here!". They then laugh and look at each other. Perfect :¬)
Fourth: 85/1.4 written all over it :¬) Nice framing and smiles. Again, interaction between them would work wonders here. This is the kind of shot where the couple looking out of frame would work well.
Fifth: this kind of shot is suited well with the couple walking together, either towards or away from you. You have the same elements, as a posed/still version, yet it adds depth and movement.
Hope this helps dude!
Edit: the colour versions need WB adjustment, overly warm and a tad over-saturated :¬)
