Not this image in particular, but she does lend herself to an Art Nouveau style.

While this image draws on ( oh dear, a punne) ancient cultures it is also influence by a less well known art nouveau artist, Jan Toorop :

I've heard of Toorop before, but I didn't realize he had transitioned to the Art Nouveau style in the early 1890s. His later work was much different!

Oh wow. This is illustration line art style right?
Didn't know you also drew this.

"Illustration line art" is a misleading description for these sorts of styles as you are just as likely to see these sort of styles in colour and animated. It is a Shape based style - (usually) 2D - as opposed to a Form based style - 3D.

Shape based styles came in with "Modern Art" movement and eventually became popular in book illustration and then limited animation starting in the mid-late 1950s and still popular. Earlier animation was based on 3D Form construction drawing - even the earliest cartoons were based on 3D Form ball bodies and tube limbs. So Bugs Bunny - 3DForm based ; The Flintstones - 2D Shape based.

Some of my favorite artists on FA use mainly 2D Shape based styles :

i spent many years working on Shape based series, usually for Hanna-Barbera, so yeah, i've drawn lots of this stuff, as well as abstract art, etc.

2D Shapes and 3D Forms are both areas for an artist to develop skills in and are complimentary : 3D style artists use 2D Shapes to compose their pictures, light and dark areas, and even brush strokes ; 2D artists use 3D lighting effects to bring a sense surreal presence to what should be "flat" pictures.

Early cultures mostly used Shape based art for frescoes etc, but some time in ancient Rome they started painting in shadows, hi-lights and Form. During Medieval times a lot of art went back to a 2D style, and then with the Renaissance the 3D Form style became the norm. Art Nouveau and Art Deco brought back in 2D Shape based designs for printed books, posters, etc - and the various Modern Art movements focused on "flat picture planes" ... etc etc. Art History is fun and weird.
