I decided to tweak Maera's deer design a little, so I drew this up.
I realized I should have drawn a thing to show the markings around her eyes better. x.x;
As a deer, her tattoos (on her left shoulder and belly) become markings, and she also has goldish markings on her ears and right leg to resemble the earrings and arm band that she normally wears. The black on her legs represents the boots and gloves she normally wears (besides the fact that the secretary bird pelt has black legs anyway). The only white on her is on the underside of her tail, and also on the inside of her ears.
Her back legs are like that because it's similar to how her feet are in her humanoid form, because she's half demon.
She's supposed to have the DotD antlers, but I guess I'll have to wait to get those.

Ignore the poor anatomy and the messy lines. x.x
