You may well have felt out of your comfort zone, Gareth, but it's not obvious. Referring to the blog post ...
First one has too much flash for me and it's killed the ambient, which should be a big ingredient of any room shot with a Xmas tree in it.
Second one's fine (but see later re cloning distractions), as are all the rest down to and including the first b/w.
That small upright dance shot is a reject AFAIC. Your timing was way out.
Second b/w dance shot's also a missed moment - albeit technically it's good shot. But what's the point of that picture when you've got the next (colour) one to show?
Kiddie dancing is excellent technically but again it's a very near miss.
Next two grinning shots are great and although the last picture's decidedly iffy (timing again), it's OK if that's the best you got of the bride dancing with her mates.
Overall IMO your setups are fine apart from that room shot, but your timing dropped off when things started moving. Were you using second curtain synch? Whatever, that's the exact reason why we never got into off-camera flash at weddings - we couldn't perfect both the technique and the observation/timing to the degree with which we were happy with both, and beyond a certain point, it wasn't the technique that mattered to our customers.
Ref distractions and the cloning out thereof, the answer to Shaheed's question is that some do, some don't. There are those who obsess about anything they see as "imperfections" to the point at which they send a bunch of files from every wedding to India with great long lists of cloning to do on all of them. And there are those who abhor the very idea of zapping a passing fly or a significant bird turd on the grounds that they're into Telling It Like It Is (even though that telling doesn't include how much they influence some of those 100% PJ shots at times).
My own rule of thumb was what's in the picture stays there unless it's something which stands out like a dog's balls, it immediately distracts the eye away from the subject and/or slows down the "reading" of the picture, it's small, it's entirely irrrelevant, and it's a doddle to get rid of. A good example would be that green reflection over the speaker in the dance shots.
Therefore in that first shot above, I'd zap the door buzzer but leave the board, on the grounds that AFAIC the latter is far enough away from them and it's much the same colours/tonality/density as the surroundings. What does get to me though is that really weird slide thing in her hair, simply because it's straight - and you never, ever, see a long straight line in a Western bride's hair ...
