The image is a composite of two distinct illustrations, both featuring dark, gothic, and futuristic themes. 

On the left side, the artwork is a digital drawing with a dark, gritty texture, rendered in muted, earthy tones of black, brown, and dark grey. Three figures stand in a desolate, shadowy environment. The central figure, a tall, slender woman with long, flowing red hair and a gaunt face, wears a high-collared, black, armor-like outfit with intricate, metallic details. She holds a large, red, sword-like weapon. To her left stands another figure, also in a black, armored outfit with long, straight, red hair, holding a smaller, more angular weapon. The third figure on the right is shorter, with shorter hair, dressed similarly, and holding a weapon similar to the central figure's but smaller.

On the right side, the artwork is a black and white, ink drawing with a more detailed, graphic novel style. The scene appears to be a futuristic, post-apocalyptic environment with large, puffy, dark clouds or structures in the background. The central figure is the same tall, slender woman from the left image, standing on a platform or pedestal.
