Man, I hate to say it, but I can't find one of the bunch that I like. But here goes CC.
1. Not sure why you put the bench in focus, it makes it the subject of the photo and draws 90% of the attention there, instead of the couple, which is the main part of the shoot.
2. Did you have them "fake like they were walking"? Seems like it, as he is rather flat footed, but in a walking position (if that makes sense lol) along with an awkward expression. Is that a phone in his pocket or is he just happy to see me? lol Try to clone out the bulge of the phone is his pocket.
3. Meh, doesn't strike me negative or positive.
1-3 ... seem very underexposed, probably due to your post processing or whatever you did to add that yellow/dingy/sepia tone (Which, btw .. doesn't work for me)
4-5 ... holy BRIGHT sunlight, Batman! 5, why did you have him in that horrendous shadow? The composition would have probably worked, I like it, but the shadow/sunlight kills it.
6. Cute picture, lots of 'emotion' inbetween the two, plus they both look comfortable. Maybe crop some of the large amount of dead space above.
7-8 .. harsh shadows again.
9. Like the idea, although he is a bit dark in the shot.
10. Again, good idea but the wide angle distorts the top of the pole so much that it looks funny and draws the attention from the couple.
Sorry I was so negative, but I've seen a lot of your shots come out great ... just felt these didn't match what you're capable of.
