#1. It is almost there. I do like a good walking away shot. Be careful about cutting off their hands. Besides just cutting off at a joint of the body, you are losing the relationship between the couple, especially with a newly married couple by not showing the hands being their point of interaction. I do like the tall grass and the wooden posts that appear to be some sort of vineyard.
#2. Composition is good. I like that we can see that the bride is holding/reading her note and the groom has a great expression.
This image to me is not usable as the groom who is the obvious subject is way out of focus. I am not sure if you focused on the note or his jacket due to where your AF points are located, or if the relationship between your camera and lens is way out of wack. I don't think that the issue is shutter speed as that lens has 3 stops of IS.
Keep shooting, you have a good eye for composition.
BTW, welcome to POTN and i hope i was not too harsh.
