‘Z’ is for Zombies

Project Z: Friendlier zombies

Back when I originally started sketching for ‘Project Z’ I was unsure of the direction (and still am), so I did up this friendlier version.  The kids love it, but I’m on the fence.  Thoughts?

Perhaps I’ll try redoing with stronger ink and spot color but keep the cuter zombies. Can I have my brains and eat them too?
