Design of a feature image/ banner for the app store

Hello, I am creating a wedding app that soon will be uploaded on Google Play. In order to do so I am looking for a classy, yet catchy feature image/ banner that describes with pictures and maybe even words what the app can do. What can the app do? Track budget, store communication with vendors and invoices, Track Task Status, Keep track of guests invited and attending and any food allergies Keep track of rentals Keep a list of DIY, Have an inspirations section in which fotos etc can be saved in order to picture the wedding in every single detail Keep track of all vendors, with whom you are or going to be in contact And last but not least create a table seating plan with all guests attending. All in all, this app is everything you need to plan your wedding and to store all important information, such as invoices, communication and ideas. Once upgraded you may even share all your information with your close friends and family and therefore export and import data. All this combined allows extraordinary customer experience. Attached you can see a print screen of how the app looks like. Should you still have any questions, do no hesitate to contact me. Regards, Kristin
