These are really good heip! Commenting on them specifically,
#1, the white vigette is not something you see all the time, so its a nice change of pace. But I think I would have chose a black border. Just my opinion.
#2, Beautiful, but pretty bright. The soft glow is well done.
#3, Great use of fill light. The ocean looks appropriately soft and romantic in the background and does not overpower the subjects.
#4, Nice closeup, but maybe a bit too soft on the focus.
#5, again, nice use of fill light.
#6, Nice tight crop, and good post processing. The black border works very well I think.
Good looking couple, and I agree, I think she will make a beautiful bride. Well done!
I really like #1 & #3 the best. Your shots have a dreamy look to them that I like. I'm not sure about the last one only because they guy looks like he has no neck.
