Inexperienced designers, or authors who attempt to make their own covers, tend to make these same common mistakes which make it look like an amateur design.
Trying to match all of the details perfectly
For the most part, cover designers are working with stock photography, unless you happen to find a designer who can do custom photo shoots for you. Therefore, the designer can only use what already exists. If you want a particular item/person/animal on your cover, there may be times you have to compromise the exact details in order to create an effective cover. For example if you’re putting a dog on your cover, yes you’ll want to use the same breed the dog is, but the dog might not have the same markings as what’s described in the book. Most readers aren’t going to care enough to look back at the cover to see if the dog matches the description in the book. If you’re using a silhouette of a dog, sometimes you may have to use a silhouette that looks like it could be the dog even if it happens to be a different breed.
Also keep in mind that although designers can alter images, we can’t change an angle an object is pointing, or we can’t (at least not easily) change clothing, or the position of someone’s arm or body, so using an image that’s more powerful can be more important than using something that 100% matches your story.
That said, you don’t want to be so far off that you mislead your readers, so you have to find the right balance between the truth and a cover that will sell your book.Read More »
