Personally, I think collectively our class did a much better job redesigning Rex Stout Nero Wolfe series book covers. The covers I've found online tend to be a bit dated, dull and uninteresting. I think book covers for mystery novels should be conceptual -which I think we did an excellent job! The covers are very literal and don't engage or intrigue the audience. The cover art work is a dead give away. And quite honestly once you read one, you can most likely figure out what the rest are about.
