Help me select a cover picture for my new coloring book!

Hi everyone! Your opinion please! Which one do you like best for the cover of my new book?  1, 2, 3 or 4? (it'll be half colored). The book will be, "Unleash Your Inner Beast." Out soon. Thanks so much for all your support!!

"Unleash Your Inner Beast" To be Out Soon!

I'm really excited! My coloring book will be out soon on Amazon. Here are some of the pages (of course they'll look better in the book). What do you think?
