Draw me a fantasy book cover with a dragon. The wearer of a golden bracelet in the shape of a dragon, a boy, is in a dragons treasure cave with his friends: an old magician with curly hair, a fancy prince, a walking tree-soldier and a knight (bit silly). The white dragon spits fire on them (he will turn out to be good, so he is startled - not a mean face, no mean eyes). The dragon is actually a king, cursed to be in this shape. So the dragon is a benevolent, majestic white creature who is extremely pissed of by intruders in his treasure cave.
The kid who is the magician's apprentice is desperate and protects the tree soldier (who would obviously burn) by holding his left hand with the bracelet in his front as a reflex action. The magic of the bracelet starts a green protective field, like a energy shield, keeping them safe.
I have added a drawing suggesting how I pictured it. Please make your own illustration, this is only for you to understand the idea. I used whatever pictures I had, just to have a picture in my head.
I will be thankful for a design that I can use lifetime on books, web and so on. I will only answer to offers that name their price before starting to work (flat fee, all-in, including lifetime publishing rights worldwide).
