Davwav,
I liked the transition from the initial puddle to the wedding but perhaps too many transitions using the puddle.?? Thematically, it kind of makes the rain as big of a theme as the wedding but clearly that is not the intention - only the context for the wedding. Which brings me to my other thought - is there some way to put across the idea that the rain is a good thing. To many, rain on a wedding day is horrible, rain is gloomy, sad, depressing etc... It can also be romantic, but I'm not sure romance is established in the rain shots (which are good, the only thing is the same shots could be used to start a horror movie - know what I mean?). I don't know how poetic you are. Perhaps a few lines of text that might establish the romanticism and put across the theme of the wedding unfolding in this context. Maybe add in a few other thematic elements: candles, the church etc. so it's not as focussed on the rain.
Good work!
