I agree with Heip. The first one has no connection, the second is better but the male isnt in focus. this type of image can work but he needs to be back further and looking at her, he needs to be part of the background, he isn't, he is too prominent and is fighting for attention, its almost like he's photobombing a portrait session. 
couple portraits are about the subjects interacting with each other in some way, in every shot. in its simplest form they need to be touching or conveying closeness.
the first one would improve greatly if they were closer, the second, besides having him in focus, just put his left hand on her shoulder.
