I like the first 3 but #4 looks like they have gone way past engagement to consummation and I agree with the other comment about #6 why cut off his hed? it looks like they broke up and she tried to cut himout of the picture.
#6 is my favorite. Great processing on that one. But I keep wanting to see the rest of his face. ;-) Do you have one where his whole face is next to her?
