You have a nice start. First I am not really a fan of the processing but that is your style as you choose. You were able to capture some nice, genuine moments between the two of them but I would have liked to have seen one or two with a simple pose looking at the camera. Your backgrounds are really busy (especially in #7) so it distracts from the subject. #4 looks like he fell into her face, he is all smushed up into her. He is also holding onto her side for dear life bringing attention to a fat roll (not to be mean since she is not fat but it does catch my attention). Anyway, like I said, it's a nice start. Keep shooting and you will get it with time.
