How is the artist represented?
At the beginning of the video, the colour of the setting is mainly white also the artist is wearing white and holding white flowers, this suggests pureness and innocence. This theme continues throughout the video. Her facial expressions also shows how than she is happy to be out of the relationship, with quite a happy and smug look.
What conventions does this music video follow?
There is a main storyline that the video solely focuses on throughout the whole video, this is both conventional and unconventional, as usually they do have a story but they focus on other things such as live action through the video. There is also quite a unconventional section where there is, what is made to look like, retrospective footage, this is a 'home video' effect where it shows how there relationship was.
How does the video relate to the lyrics?
The video strongly links to the video, in that the story line is linked to the lyrics, about her 'finding the good in goodbye' and ending in a relationship and the footage is of her in her wedding dress realising that she made the right decision with not being in the relationship anymore.
Ideas and inspiration from the video?
My favorite part of the video is how they use the retrospective footage to portray her feeling, this could be an idea I could use. The way the colours all link in are also something I will probably use.
