The pieces in this link are created by Mytherea, so you must follow her (easily found) rules. It’s not a hard chore either, she’s really easy to work with. ^^
The pieces I’ve currently found most helpful are: Clawed Hands, Everything Concerning Noses, and Everything Concerning Lips.
She also has this lovely pack of parchment like textures and many leather ones, if you happen to be searching for that!
Also, I must link to her full gallery. It’s full of excellent pieces and is quite fun to go through!
