Тony, it's nice, well done, conveys the emotions precisely...

But yes, it does look pretty simple, still imo
simplicity is a plus, it's easy to understand the context of what and how is it happening!

I am sure for the couple and their relatives, it's a masterpiece, they are going to love it for sure!

Yet, is it a creative statement, a novelty in wedding video? Probably not, many of us strive to produce fresh visual language, using all kinds of means available!

Too much slow motion diminishes feeling of aliveness of a wedding, in my personal opinion,
otherwise your piece is nice!
