Cover to Cover - Why I needed "Teen Monster Hunters" darker!

Saturday had been creative change day.

Closed the story line on another RomCom romantic comedy  (What do you think about the tagline: "Three friends, one startup, one vow: no romantic distractions. Yeah, right!")

Decided what to write next, continuing the Teen Monster Hunters series with the next 50K word novel, working title "Teen Vampire Hunters".

Changed the cover of Teen Monster Hunters. What? Why? I felt, the cover was too bright and cartoonish. I like the cartoon concept, to the extend that it will be a recurring theme for the next books and novella short stories. But for monster hunting story, the color scheme and cover should be slightly more edgy and scary. 

Before and after. What do you think?
