The reason people don't want to try is that you haven't specified what you are looking for even after having a few different banners made.
Spending time making something that no one wants is wasteful, particularly for me, as I don't have the time to spare, constantly remaking.
If what I made earlier was somewhat to your liking, you could specify what you want changed and I could retry. However, retrying without knowing what you want is silly.
Regards.
