I really like the video. Your white balance is a bit red for my taste, but I like it.
You have some nice stuff in the ceremony. They only thing I'd say is to crop tighter. Show that emotion you worked so hard to get. It's beautiful and it should be shown.....bam in your face cropping....
There are a few you should crop really strong. And a few I think you should do color jumps on. A few changes on stacking for formals. (They are sometimes really lopsided). But I really like most of them. A color bump would really help them pop. JMO.
The formals with the couple need to be bumped by a stop. Again, just my opinion. But I like them. You have some very artistic stuff with the couple with I think is awesome.
I like your video. It's also gone off white balance, It's too blue, too red, but it's still good.
Never show the bride eating. Never show anyone eating.
When photogs switch to B/W I always wonder if they did that because they couldn't fix the white balance. I hope you give your clients color and b/w.
Cake shots are amazingly good.
Overall, my feedback is that you have some cropping issues and white balance issues. However, overall I think that you did some really great stuff. You have a lot of wonderful moments.
