Here are my final ideas, I wanted to develop both further as they both have strengths and weaknesses.
Improvements I’ve made; enlarged the badge and cleaned up its sides, added more shadow to make the badge come forward and altered the shirt so it’s no longer straight giving it a bit more life.
The sheriffs badge works well on its own and works strongly with genre of the audiobook, however I’m struggling to develop a background. I fear the badge on the jacket is too busy and I may struggle adding it to a banner effectively - potentially I could illustrate the rest of the cowboys shoulder.
The toy gun works well as a fully rounded idea, both the cover and the banner, however I fear the concept is lost in the cover itself as it is a close up of the entire object - perhaps I will do a survey to see if it’s recognisable.
Next steps- try the needed elements (the audible banner) on both designs to see how they look as a completed identity.
