Ninjas of many faces - crochet

I crocheted up these ninjas and decided to give them different kinds of faces. So theres the angry ninja, the cool glasses ninja and the happy ninjas in there too.

The pattern I used to make these can be found in the book Creepy Cute Crochet by Christen Haden.
I warn you though this is a good book but not a beginners book. They don't have instructions on how to crochet in this one, and you will need to know things like: magic cirlce, increase, decrease and be comfortable working in the round.
