I am open to your ideas because you are good at what you do. The only other idea that I could come up with would be to split the cover Image so to speak. The face of the wizard instead of being in the upper right would be in the upper left .on the front cover and in the upper right on the back cover. The scene on the back would be a flip image of the scene on the cover.
Hello Bob, see the attached sketch. I had planned to place the text at the bottom. It will look impressive in the finished cover: Heavy realistic clouds, the feeling of the wind. Hope you will like it. Best regards, Ruslan
