I don't know that anyone's opinion counts for anything except the customer and we can't interview them.
Here's logic. Your book cover will appear in thumbnail size all around the internet. If you are good with people not being able to read the title or your name in thumbnail size because you've designed it extra special artistically, that's your choice. It's hard enough to see the thing in thumbnail even if you try hard you might not be able to read the text.
Some people will reflect on this point and other people will ignore it/defend their choice practically to the death.
It's not that important. Do what you want to do.
Don't make it hard for people to buy your book. It's hard enough to get people to the book's page as it is.
Have you made the book, the blurb, the cover as attractive as possible to THEM, not to you? We don't care about you. You don't really matter. Or you can matter and have complete sway on another book. What if you only have 1 book? Do it your way. This is a learning experience for everyone. Either you will learn or you won't.
I'm changing Her Cold Kiss around because I don't think anyone understood it. I'm not devoting vast amounts of time to it but the fixes are simple, quick. Digital publishing means not only attending to what's in the future, it also means attending to projects in the past.
