Themes and ideas before storyboarding

Before I began my official storyboard, I thought I'd note a few ideas I came up with to add to what I eventually come up with.

Themes: Every song has its own key theme to it; a majority of acoustic songs are about love or a past experience/memory, so I think key themes for my music video should be about love and time/age.
I recently watched the video for 'The Scientist' by Coldplay for inspiration for my theme of time as I love the way in the video everything is going backwards instead of the usual straightforward course of a video. I thought about using this in my video, for example, instead of the character walking forwards, they walk backwards and their surrounding also do this, or the subject may walk forwards and their surroundings go backwards. I also thought about age, and maybe the subject in my video ages throughout the story? They may grow older or younger (changing the actor for a younger or older actor that resembles the previous one), but it's an idea that needs developing and is in early stages.

Balloons: As the 'Sarah /minor' is quite a dreamy, 'floaty' song, I wanted to somehow incorporate the use of balloons in the video I will make. Generally, everyone likes ballons: they can connote happiness, youth, fun, celebration (birthdays), parties, childhood, and even hopes and love, so the use of balloons in my music video could imply any of these things.
Also, as male artists appeal to a mainly female audience and attract female attention, I will try and make my video slightly more suited to that of a female audience. To continue my idea of using balloons, I looked at existing media products, such as adverts, that incorporated balloons in them so I first looked at the 'Miss Dior Cherie' advert:

   

^The magazine advert

^ The Television advert (Director's Cut version)

I love the use of balloons in these adverts; I like the use of colour, and I like the lighthearted, dreamy atmosphere that they add to the already cheerful and 'fun'advert. I like the idea of the balloons floating away (I also like the idea of the character floating away with the balloons, but it would be far too hard for me to recreate!), and I thought about something along these lines happening in my video. I also had the idea of the balloons popping at the end; the balloons floating away would be quite a peaceful ending, whilst the balloons popping would make more of a dramatic ending, so I will consider which version I will use for my video.
