Official ref for my fursona, Nicolee.

This reference shows markings, different hairstyles and preferred dress style.
Innards are the teal blue color but Nicolee's blood is bright cherry red.

Nicolee's design is very fluid and can be drawn in many different ways. Plantigrade, fatter or skinnier tail, longer or shorter ears, different horns and even the muzzle can be drawn differently. As long as it's still noticeably Nico.

Because I am a gender fluid person and some days I feel more of a male than female, or even neither, Nicolee is like that too.
They can be drawn female, male, both or neither.
