Try something new, out of the box. I notice with your style of wedding photography you have a unique look. Try different processing. Or look to another set up for your lights.
A good place to search for inspiration is on the web. Even on here; look at different styles, different angles, different processing..try a new conversion BW method. Learn a new skill, invest in renting or buying a new modifier (ever try using gel filters? Those are always cool and fun, how about a beauty dish? Striplight? They're only about a hundred bucks or so...claim it as a business expense).
Talk to your clients about what they want, if they've got sample photographs on the web they could link you to of a style they like...I'm sure you know the wedding world better than me, though, I can offer some general advice. I like to sit down with people and talk about their work, or their kids, or their experiences with prior pro-photographers/agencies. See what they like, what they don't like, what they wish they could get from you that they didn't get from the last guy....etc.
I like these shots, in here, except for set #4; lower right hand corner image...I feel the skies are way too blown out, and the couple look to be blurry..that said you never know, as the jpeg conversion method could be the fault of the softness.
