Mom --- I totally agree with you personally. On the other hand, professionally, I suspect they're right....
Sara --- I think you're spot on. After all, if I wanted to just preach to the choir, I wouldn't be publishing a print book, so I'd better reach out to as many people as I can with the cover.
Justus --- I know where you're coming from because that my was first knee-jerk reaction. But they didn't complain about all of my muddy, realistic pictures inside the book, so I'm going to figure the cover is an advertisement and not really part of my artistic piece. If yellow boots make people pick up the book, I get a chance to sway them over to being non-yellow-boot people.
