She has a long, slender neck and an hazelnut forelock hanging over an eye, which she regularly blow away annoyedly with a little huff. Tall green eyes with very long eyelashes, very expressful look at the world around with an empathetic gaze, but... there is something wrong with these big blinking eyes.
The creature you're looking at does not seem stupid, nor does she seem to be lacking a mind, but her eyes reflects a utmost naivety, and she looks at everything around her like it's all the first of its kind she spots.

Her body sports a light, silky hazelnut coat, her hair being just a shade darker and her ponytail, yea, the one all the way back behind her hindlegs that she can fawn, an even deeper caramel hue.

her legs end up not in feet but hooves made of horn, but also has a pair of antlers growing out of her skull.

You're looking at a Centaure Dryad.
