I'm going through all my deer, drawing references, and updating their look to something more mature.

This is Artemis. The only major change I've made to this one is adding hair, because quite frankly, hair on humanfaced deer really works for me. xD When she has the skull on, she tucks it away. ...because she can. It's supposed to be an auburn, red-brown colour, curly hair.
The other things I've done are: changed the skull to make it more obviously ill-fitting and not hers, and taken away the lower jaw to be more pleasing aesthetically. The side-prong things were always there, but if you didn't know about them before, take note.

The wristblades are supposed to be designed so they scrape it Artemis's front legs when she's stood normally.

I've also changed it so that she only wears the skull when going on a rampage.
