Changing graphic designs for iphone game from iphone 4 to iphone 5 size

C'est ce qu'une entreprise en/au(x) Australia recherchait pour leur app design

I currently have an iPhone app on the appstore called lead balloon. I have correct background sizes for iphone 4 and ipad but the background for iphone 5 looks cut and pasted.

I would like iphone 5 background sizes to be done.

There are a total of 14 images to be done.
Below are just examples Voir plus
