Narnia book sets

Looking at the variety of book covers designed for this particular set of stories shows that there's potentially room for more. Although the story stays the same amongst each design, the covers change, and it's almost so it targets a different audience. There are childish looking designs which appeal more to the younger generation, and there are sophisticated designs which appeal to a somewhat older audience.

I want to bring a more modern and contemporary style to these tales. I want to show simplicity amongst them instead of full blown imagery. I understand this is a magical fairytale and so full and pretty pictures portray this easier, but I want to come in from a different angle.
