I like the capture (prom?) but I wish I could see the fellow's eyes a little better so really see the affection between the two of them. The harsh light is a little distracting (the shadow of her chin on the flower).
I love this. The crop is perfect. Don't let people tell you to always include the whole head. DOF could be just a bit deeper, as the girl is just a bit less sharply focused than the boy.
