I incorporated lightning into the Z of Wizard. It is attached. I've been looking for how to do it better, this version is most appropriate.
Regarding the first book cover. The tornado would come from Wizard's mouth with his cheeks blown out - it's an original idea. Of course, need to make a sketch. If to make that in a dust jacket format will be a lot of empty space on the back cover. What do you think is it possible to depict there? Or you leave it to my discretion?
