Final product- Initial idea's

I have decided that for my final media product i am going to create a promotional poster for a television series. I will create a scene which will leave the audience wondering what is happening, this will make them want to watch the programme. Using the skills i have learnt from visual communications i will compose a scene for the main image of my poster. I will take into account, form, colour, composition and framing. This will enable me to create an effective media product.
