Very interesting image for the at work challenge they both seem very relaxed and quite at home in this setting. The focus and dof are both good, the colors are very eye catching and well bounched out.
There is one tiny problem with lines as you look at the photo your eyes are drawn off the couple and to a person sitting in the background, simply cause of two leading lines running directly into this person, the black post in the foreground and the red wall accent coming down in the middle of the photo both end up on the same person and take attention from the couple in the photo.
The photo is very well done and does meet the challenge, definately a lot to look at in this photo and yet not overly cluttered.
I needed the title to make me realise this was somone at work - he doesn't look like he's doing his job, just posing for a picture. Nice shot of him but the girl caught mid sentence doesn't seem too flattering to her.
