Hand-drawn cover

Hand-drawn cover

Our new book, "The Pomodoro Technique Illustrated", contains hand-drawn illustrations on every page. This cover is drawn in that same style. What do you think of it?

  No, not at all Not really, the cover doesn't do much for me Maybe, it's kind of interesting Yes, I'm hooked
I would be interested in reading this book based on this cover.

Should this image be used as the cover for the book?
