Wow nice shots. I only have two suggestions.. Only minor.
A little more seperation between your subjects and the backgroud would ease the shadows that are cast and also maybe bounce a flash from the roof to try and eliminate shadows from behind his ears (or cut them off ) and elbow.
Like I said, it was just a bit of fun but Danielle and I are really pleased with how they turned out.
I note your point about the shadows, Moose, but I found that moving further from the wall made the shadows worse. There is a big angled skylight in the room and it made bouncing the flash quite difficult. I need to save up for some home lighting set-up!
