I've read that authors are best to leave the cover-art to the 'professionals' who are skilled at graphic design and know what appeals to the masses. But when I look around in a bookstore, there are so many books with just horrible covers. If an author has a particular scene in mind, can you ask the cover designers to sculpt a particular scene? Or can you hire artists that you know that you know would do a great job? I just think it's a little strange that an author doesn't have priority when it comes to the creation of the cover-art... Thanks in advance.
