Hi H
I like the first and third images
, some of the others the back ground look a bit busy for my liking .
The one of the couple snogging looks like a car add and the the last pic looks like she's worried a baby bump is showing.
maybe crop out her hand.
If its not skin tones what makes the 5D better for portraits ?
Hope you don't think I'm being too critical your shots are better than ones I used to do at weddings when I was young and silly enough to try to make a quid from it.
Wedding photography has to be the hardest way to to make a quid in photography , If you can do it , make a living and keep your sanity more power to you.
