The image I had in my head for my book cover didn't necessarily work in reality. Running a 99designs contest allowed me to see that and, with the professional input of several hard working designers, make changes that worked and view them. Between the six designers to enter, I received a raft of cover images, including some that stepped outside the brief to great effect. I was able to get outside feedback using the polls, make changes and ultimately find the perfect design that was similar, yet so much better, than my original brief.
