That typographical hammer design is amazing, but I think the final version you (or they) chose was the best for a book. The characters' silhouettes convey a lot and give the reader something to identify with and puzzle over right away.From a pure design perspective though, I'm nuts about that name-hammer.
Heh, I knew that hammer name idea wouldn't win the cover but I just had to mock it up! They chose one that fit the story better (which they've read and I hadn't) Though I do like the odd colors on the fourth concept. I coulda seen that going all the way.
