We all have some book covers that just completely irritate us and those covers may make us choose to not read that book. Here's a few of my book cover pet peeves.
1) Strange or obnoxious focal points.
This one might just be me, but if a cover is overly strange I really don't want to read the book.
2) Covers with the same picture as another book.
3) Covers that look like they have two pictures pasted together.
4) Models with with strange expressions.
I know some people agree with this if not most people, because really? I don't want to see a picture on a cover that you spent five minutes shooting for.
5) Bodies Without Heads
