NoFaceNoProblem

Hi Everyone! I am designer from Toronto, Canada and I am designing a few Studio Ghibli Enamel Pins. However, there is a slight twist. I'm a big Samurai fan and so I thought it'd be cool to mix up my two fav things... Samurais + Ghibli = I have already made 8 designs which include (No Face, Haku, Totoro, Cat Bus, Mirrored Haku, Moro, Chuu & Ko, and Boh & Yu-Bird.) So i'm pretty happy about 7 of them and they are already locked in. I was hoping to get some feedback from you guys, maybe even another design idea? However, I wrote this for genuine advice on this design, and would love to hear from you guys Just to get an idea of the theme, here are the other designs
