I have deliberately chosen simple text-on-plain-background covers for my books because I like the simplicity, and find them fresh and different. And some others have commented saying the same. However, just as many others have suggested they could be seen as amateurish or rushed, and this could affect their buying interest (even if free).
So, I was wondering if you would let me know what you think? If you’d rather do it in private please feel free to email me. But please, your opinion will help.
Below are samples of my eBook covers.
