Death of a Serpent: Historical Mystery book cover design

I’m remaking the book cover for Susan Russo Anderson’s “Death of a Serpent: A Serafina Florio Mystery”. The first cover is a little boring, with simple text and flat colors. I didn’t even notice the top half is a girl’s head until much later, and the division is a little awkward.


Keeping the same basicĀ  style, I started with these:


Not bad, but Susan suggested a blue-green background and thick, bold text. I’m loving the blue, some of these work pretty well, although the placement and balance isn’t ideal yet…


The last one looks most like a standard published book to me… what do you think?
