I think whatever sort of diffuse glow you put on it a very bad looking, and due to that or a selection, there's quite a halo around the two of them. The whole image has a very soft/out of focus look to it. The dress is way too bright and the tux is way too black.
When shooting people kissing, the moment before the kiss, or just when their lips barely touch is far more romantic and much better looking than when their faces are mashed together. And why is his leg up? I think it kinfd of makes him looks like a stork, or more like a vulture with the way his neck is craning over his stooped shoulders. People with really bad posture are hard to make look good in photos. Especially when they are leaning over to kiss their bride. Any time you can get the bride up on something, like the uphill side of the ground, or on a step or curb or whatever, it can help that a lot. Keep at it!
