Design a corporate imagem (not a logo)

Hello, my name is Arno, I'm from Brazil. One of my biggest client need a new corporate image. It's an image we will use along 2 years. My client it's a fashion mall. What I'm looking for is a powerfull image that convey happiness mixed on a fashion style. I've just uploaded 2 images. The first one is the current corporate image. The second one is a mockup for the new winter campaing. If you can do better than this, I'll be happy.
