Bat colorscheme ideas (Patreon)

Going with a cute, non-realistic design for the bat. Decided to collab with one of my fav artists for the concept art, you guys are going to love it. 

Wondering what type of color scheme I should make the example in (if the pattern is simple enough I might make more than 1). 

Fruity? Starry? Natural? Pastel? I'm open to ideas
