Olympus EM-5 & kit lens portraits

I have a wedding booked for next month, which I plan to shoot with the EM-5, coupled with the 14-42mm/45mm/40-150mm trio of lenses. (For those SLR traditionalists who are gasping in horror, don't worry, I will carry a 50D/24-105 combo as a backup, just in case...)
I have been trying to get some practice in beforehand. The el cheapo 14-42 kit lens does a pretty decent job IMHO, and the touch screen focusing abilities of the EM-5 are excellent. Here's a few recent practice shots, all taken in available light:
