All we can say is that banner A triggered more clicks than banner B. So you can stop here, and enjoy the 2,29-fold traffic increase. However, you can also continue testing, to check what element caused the extra clicks: the hand-drawn image, the running boys or the tangibility of the final product. 

There is a nice way to check what advertisements other charities (or your competitor) use. It is called the Facebook Ads Library. Here you can e.g. see what ads they currently run and how the Facebook ads of this charity  have evolved over time. Try it here for 'Wilde Ganzen' or any other charity, like Save The Children in the US.
