Seeing as the OP wanted comment and I have nothing better to watch on telly as wifey's finally having a rest and has stolen the remote
First of all - a good set of images by someone obviously competent in their photography, just a couple of pointers if I may
1 - the composition's not right for me as they are around the centre and the top of the image isn't doing anything interesting, so its kinda split the image in two. Chop off the top down to where the big branch on the left starts and you've put them on a 1/3 thereabouts, both down a 1/3 and a 1/3 from the left placing more emphasis on the water (which is more interesting than the trees)
I'm not convinced that building's walls are perfectly vertical, but my biggest problem is the birch growing out of the Groom's head. When concentrating on everything else about a shot its all too easy to miss the background, so always look past the subject and see what crap is behind and reposition them or yourself
Lastly (ignoring the PP) there's an old saying in portraits that goes
'If it bends, bend it' - so always try to avoid straight arms, as here with the Groom - even sticking his hand in his pocket (cuff still showing) would be more attractive, and if they'd turned into more of a V they could have held hands too, which is usually nicer than square on and straight armed
2 - lovely shot, genuinely looks like they were walking along and suddenly called back by a friend. In this light, a wee dodge on their faces and eye sockets may help
3 - another nice shot. The branch jutting in top right looks a little more like a mistake than the design I'm sure it was. This is as the shoot-through of foliage is generally used to suggest a candid capture with the couple looking at each other or anywhere but at the photographer, whereas here they are still looking at the photographer so it looks more like a mistake than intended
He has a straight arm again, and the Bride is now on the 'wrong' side again. By 'wrong' I mean its usual too to try to keep them on the same side as they marry during the ceremony, partly for continuity in the album as constantly swapping sides stands out as being odd after a while
4 - a good effort in what was probably a tight spot, but the background is intrusive in the radiator and the lighter area near the pillar just above the Groom's head. His arm has a slight bend (better) but his hand is cut-off, so it'd have been better lightly resting on the bannister. He has an odd expression too, so maybe this needed a couple more attempts to get a better one or he really is getting fed up
5 - straightening this image would cut into the back of her dress a bit, but that will actually aid composition for me, and the top left needs to be cropped out too as its distracting; but overall a lovely image and great expression
6 - had she been a tad closer to the bannister her right arm wouldn't have been so straight, and if she'd held her flowers around or just above her waist her left arm would have a nice bend and be presenting the bouquet better to camera; but otherwise another lovely image
I hope you don't mind these comments and if the rest of the day was of a similar standard then yes, some of the previous comments about Pro standards are valid. I have certainly seen worse from full-time Pros let alone part-timers (who are not necessary worse btw)
In summation - good job done their mate
