I’ve heard many traditionally published authors complain that the downside of having a contract with one of the big six publishers is that you have very little say in the cover art. I do sympathize, but in the indie world we have the opposite problem. We have all control of the cover art.
This may sound like heaven to some, but I haven’t much of an eye for graphic design and worse, I really don’t know much about covers in general. When I purchased a book last year, I never thought about what drew me to it if I didn’t already know the author. I rarely looked at a cover or thought about why I liked it or even if I liked it.
