Critique per req; It's nice ambient light image, but there are a couple of areas where it could be improved. The blown white shirt the gentleman is wearing and the white background really pull the eye away from the faces. I like the way you've framed them against the little bit of higher background, but if you'd brought even a single off-camera speedlight for some fill, it would have really improved the overall exposure. I think too, moving just a bit to your right would have helped the overall composition as we see very little of his face.
