This is my character Ixtux.
She's even more complicated than my fursona.
character © of course

Breakdown:
Fox ears, tail, nose, and hands
Oryx hooves and horns

Error in image above: The colour should only be around the black, I messed up and left some outlining the creme.

vIMPORTANT!v
The red that changes colours is bio-luminescence so its actually glowing.
Like my fursona, Fawk, Ixie can switch around with genders. Although Ixie only switches between herm, fem, and dickgirl (never goes full male. Gotta keep those breasts ;3)
I forgot to specify that she has split hooves, not horse hooves (although I did draw the split hooves).
She also has small saber fangs that will poke out slightly.
AND.
Pictures for parts I didn't feel like drawing on this ref sheet--
Horns and hair: (horns should be slightly longer and less curved, I was limited on IMVU)

More details/random facts:
Orange is also be pain and anger.
The orange will be located around where it hurts while the rest of her body would stay red.
Purple would also include unconsciousness.
The colour change inst immediate, it changes as the mental/emotional state changes. So as she falls asleep her colour would fade to purple with her falling asleep instead of suddenly turning purple the second she is fully asleep.
