I've been wanting to do a ninja sticker for a while now. While I was working at my regular job, I jotted down some notes about what I would want from a ninja sticker. My mind was thinking about ninja weapons, hand signs (ninja magic, of course), and action poses. I decided I wanted to do something different in the end.
One ninja is cool, but a group of them is even better. I have a sketchbook page I have been filling with different eyes (experimenting to get more expressive and varied shapes) which was perfect for this piece.
According to internet-meme law, I should do a pirate themed sticker at some point. I'll start kicking around ideas for that soon I guess.
