If you are interested in good book cover design, then you are probably interested in good book cover designers. But what is a good book cover designer? I suppose it is many things, but one thing it is, is a good designer. But what is a good designer? Again, many things, but among them: One who has a good sense of proportion, layout, color, composition, and spacial relationships. And maybe this person even knows a few tricks. Like putting the most color where the focal point of interest is. If the focal point of interest in the illustration above is the head of the eagle, then notice that it is the only place in the entire illustration that has all the main color groups nearby: red, white, blue, light blue, gold, maroon, black, and dark maroon. But isn’t this just style? Maybe. Another illustrator might not choose to work in that style. For example, this other illustrator might have completely different palette: More subdued or earthy tones, sepia colors, and the like. Whereas this illustration showcases all 3 primary colors in their boldest, + white, black, gold, light & dark maroon and light blue. All of that to say that in order to be a good book cover designer, you must first be a good designer. And to be a good designer, you must first be a good illustrator. Personal opinion? Yes. But at least know that if a person (such as myself, for example) claims to be a good book cover designer, then this person claims to have a good sense of proportion, layout, color, composition, and spacial relationships. In my opinion.
