After reading the brief, I sat down and brainstormed out all the ideas i had for the final piece. After a large amount of research and sketching, I decided that I wanted to make the number 20 within a level of Sonic. I also decided that Green Hill Zone from the original Sonic was one of the most famous levels, and so it was appropriate to use this theme for my final outcome. This would also fit the brief, as it appealed to both target audiences due to the popularity of the level all ready.
The piece is intended for use as a poster and billboard campaign to advertise the upcoming anniversary, how ever an animated version could be used on television and the internet as further forms of marketing.
