This looks like a tumblr meme, or something you slapped together in five minutes to display your makeup FX selfie. This will NOT sell this book, or any book. You may think I’m being cruel, but that’s the way it is: If you expect readers to spend money on, and time reading, your book, you need to demonstrate that your book is a professional production. This doesn’t do it.
Hire a professional. Even a cheap one. The fact that you’re submitting this here for critique means that you do not have the grounding in basic design needs to recognize the deficiencies in your abilities. Just go pro.
