Help with a female character I am working on

I need some help with setting up the following character.  Below is the form that the character assumes most of the time.  She does have another form that she can assume which is her true form.  How can I go about setting up her true form which has legendary beauty and have more sinister characteristics as well?

Humanoid Form: A statuesque humanoid woman walks in, moving with surety and seduction. There is something sexy about the way she carries herself, a hidden power to her movements. The well-defined muscles accentuating her flawless antique ruby skin, which possesses a luminous and metallic appearance, showcases her physique—a testament to her strength and femininity. Accentuating her oval-shaped face are her high cheekbones. Eight sleek tentacles that reach down to her waist protrude from the back of her head. Two gold earrings are worn on the top and bottom of both of her pointed ears. Resting between both of her eyes, which have a black sclera and glowing antique ruby iris, is her perfectly shaped upturned nose. Her full lips possess a cupid’s bow. Each one of her hands and both of her feet possess six digits. Over the black leather cropped corset top, which beautifully accentuates her huge breasts she wears a black leather bomber jacket. Piercing her belly button is a small naval ring. Her long, sexy legs and perfectly rounded buttocks are shown off in a pair of low waist black denim shorts.
