Proposal of advert

For the advert we are going to be making, we are aiming to sell a soft drink. We are trying to achieve capturing the audience of 12+.
Our main idea is to use 2 actors, this will include Nathan starring as the main actor in the advert and then either me or Amber being the second actor who is going to be in the advert at the end for 5-10 seconds. Our idea for the audience is going to be Nathan starting of dressed up in some kind of costume/wearing a mask looking odd/freaky walking up the stairway expressing an miserable genre for around 10 seconds. Then afterwards the idea would be for the next 10 seconds he will reach the top of the stairs and be worn out/miserable and then me or Amber will appear in the shot and give him the product we are trying to sell. Once Nathan drinks this he will then change out of the props and go back to looking normal and looking a lot happier than before. Nathan will then walk on looking happy with his drink. We tried using Coca-Cola's motto open happiness. The point of this advert is we are trying to show before having the product he is a really freaky person but once having the product changes moods and goes back to being himself. We are going to be showing the product halfway through the advert and then a big shot of it at the end.

We are going to be using either a freaky or sad based background song for the meanwhile Nathan is looking miserable and then once having the product the background will change to much more of a lively based song.

We could use black and white for more effect for the freaky based advert whilst Nathan is 'not himself' / in use of the props but we have not discussed it as a group so I have no idea what effects we are going to be using in the advert.
