This is a book by: 1DaughterOfPoseidon

It's basically about these 12 brothers who all have magic and don't get along till a life or death situation threatens all of them.

This first cover, I incorporated smoke as magic, I know he fingernails are painted, but it is black and your readers won't notice. You wanted some spark or flame added as well, the background shows a conflict of some kind with the book being on fire. Finally, the yellow lettering and flames will catch a reader's eye.

This one is another one, incorporating the blue and black that you wanted. It is one fire, fire always catches the eye, and again I did the yellow lettering so that is another thing that pops to the eye.

I hope you like them! Here are some banners!
