Okay. Enough excuses. This is said as kindly as possible. People are trying to give you feedback about your images (on a whole quite nicely) and all I am hearing is. 1. first time photographing a wedding 2. they don't care about their images.
If you aren't happy with the product or don't want to grow from the experience and hearing from other photographers don't share them. Simple as that. Since you posted and asked to know what we think do expect to hear opinions that may vary from your own.
Even if a couple doesn't give two beans about their wedding photos you best put in your very best effort because I bet most times they won't be saying that in ten years time.
I'm going to say this point blank that there are some signs that this couple weren't extremely enthralled with having their photo taken so that does make things more difficult so I will hand that to you. That being said there are so many different ways you could have posed her to make her look like a rockstar. Simple 45 degree turn, make angles (triangles are uber nice on females although sometimes cliche), add some curves. Most importantly ahve them interact. In all of these (well, not the second) they are looking at you straight on. Even on the most fit gorgeous lady this is not the most flattering angle - particularly sitting down in a dress like this.
If a couple is not comfortable with having their photo taken it is your job to make the best of the situation. Have fun with it - have them have fun with it, make them feel like the camera isn't even there and instead they are just being documented on a date. It's weird to role-play but sometimes you have to give them situations. "Oh just lean over and give her a little kiss... oh come on (bride) you can pretend you love him!" or give them tips. "(Bride) when you are standing lean on your back foot, now look towards me, tilt your head a touch to the right and think sultry... not sexy.. sultry... perfect! Just like that!" Always give positive feedback. If it looks like crap don't let them know, just change it up right away and move forward. Positive feedback is key particularly in a situation like that.
I won't even give technical feedback without some more information on gear and that EXIF on the current images but here is a starting point fo ryou to work off of
