I like many of the photographs, but I don't like the ones where you've covered one or both of their faces. People want to see themselves in their portrait photographs.
The photo with the two of them sitting on a bike kissing would be better if you'd moved to the right so you would have seen more of their faces, and the same with the black and white photo. I would like to see a little more of her face. But other than that, I think you did a great job.
Have Fun,
Jeff
