Some great ideas and concepts. Pretty good for a second go as the main shooter!
Some things that I see:
#1 could use a little more fill on the bride and groom. Maybe adjust the exposure and blow out the backlight for more effect.
#2 has great composition, but the bride looks like she is trying to watch her step, which takes away from your image. Any shots of the both of them looking at camera or where the bride is less "distracted"?
#3 is good but perhaps only expose the bride's eyes and/or hide her nose more. It looks a little weird with only part of her nose. Her solitary bang is also a distraction and should be cloned out. Also there seems to be some light leak that is casting a warm light on the groom's flower and white shirt. Seems out of place since you shot in open shade and have no dapple light on the bride.
#4 is a great idea, though some of the wedding party looks unprepared.
The groomsmen on the far left has not fully completed his cool guy look with his sunglasses, thus making him look like he has no eyes.
The best man (?) is the only guy with his jacket unbuttoned and tie flapping in the wind.
Maybe have the bride and groom equal, with everyone else being behind them?
Great expressions from the first and last bridesmaids. Middle one is looking at the ground (like #2) and is the only one not wearing heels.
Processing is good, but has quite a bit of magenta. I would back off the magenta and warm it up with the curves.
Finally, watermark is for POTN use and not on the final images? If so, I would consider sizing them down and making them more transparent.
