    A found professional high-fashion photograph of a dark-haired woman with piercing gray eyes, wearing a luxurious black and red dress of an Aesthet design, and a (black and red hat with a large black bow on it:1.6).  She is elegant, glamorous, seductive, and yet innocent.  She wears professionally applied make-up, and is very beauty focused.  She is set (in a vast opulent art nouveau styled room:1.4) in a shadowy and moody low-contrast cinematic scene that uses soft volumetric and ambient fill lighting. Vibrant rim lighting and bold edge lighting separate the various layers scenic layers.  The photograph captures an almost supernatural ambiance with a blend of organic and mechanical elements hinting at dystopian visions, futuristic landscapes, of surrealistic situations.  This is a professional and highly detailed fine art photograph, of high quality, comparable to those created by the likes of Chuck Close and Stanley Artgerm Lau.  The image uses an almost monochromatic color scheme of reds and blacks. There is an emphasis on texture and minute detail, with dark and intricate textures.  It has a dynamic composition, uses a slight vignette, and has superb bokeh.    <add-detail-xl:1.00> <xl_more_art-full_v1:0.48> <Scaleborn_SDXL:0.72> <Robotics_-_Old_School_style_-_SDXL:0.64> <aidmaFluxStyleXL-v0.2:0.48>

    Alara Nightshade stands tall and proud, a testament to her Elaraan heritage. Her emerald eyes, flecked with gold, peer out from under a fringe of raven hair that falls to her shoulders in soft waves. Her skin is a rich tapestry of greens and golds, shimmering subtly under the light of the moons, hinting at the ancient lineage of the elven guardians of the forest. Her features are sharp yet delicate, with high cheekbones and a strong jawline that speak of her warrior spirit. Her body is a masterpiece of athleticism, muscles honed from years of combat and discipline, wrapped in an intricate suit of armor that seems almost organic in its design. The armor is a deep, forest black, adorned with whorls and patterns of leaves and vines that appear to be etched from the very night itself. It clings to her form, highlighting the curves and contours of her powerful physique. Her armor is not merely for show; it is a living part of her, enchanted by the druids of her hidden enclave to respond to her will, moving with her like a second skin. The pauldrons are crafted in the form of a panther's head, its eyes gleaming with the same fiery gold as Alara's own. Two actual black panthers, Aether and Umbra, stride alongside her, their sleek fur a stark contrast to the metallic darkness of her armor. These animal companions are more than pets; they are an extension of her soul, bound to her through a sacred bond forged in the heart of the ancient forest, hkmagic, Art by Boris Vallejo, detailxl

    A detailed, highly stylized bee, rendered in a surreal, almost anatomical style.  The bee's body is a pale off-white, showcasing a structure resembling a skeletal form, its internal organs partially visible. Its wings are translucent and airy, almost like delicate glass.  The bee's abdomen is adorned with a meticulously detailed blue and white porcelain-like pattern, depicting traditional Chinese landscape scenes.  The intricate design includes stylized flowers, buildings, and landscapes, characteristic of blue and white Chinese porcelain.  The overall composition creates a sense of both fragility and detailed engineering. The lighting is dramatic, showcasing the intricate textures and patterns within the porcelain design, casting deep shadows against a perfectly black background, highlighting the contrast between the cool white/grey tones of the bee and the rich blue of the porcelain.

    Crystara Synthetica stands tall and imposing, her crystalline exosuit gleaming in the dim light of the battlefield. Her body is a masterful fusion of ancient crystal and intricate mechanical craftsmanship, each shard of crystal perfectly interlocking to form a sleek, almost ethereal armor that seems to breathe with a gentle, pulsing light. The seams of her exosuit glow with a soft blue aura, hinting at the arcane technology that holds her together. Her frame is robust and curved in a way that suggests both feminine grace and the raw power of a seasoned warrior. Her wireframe crystal helmet is the crown of her form, encasing a face of stoic beauty, with piercing yellow gem eyes that flicker and dance with an inner light, reflecting the wisdom and sorrow of countless battles. Her limbs, though mechanical, are designed to mimic the organic, allowing for fluid movements that belie their metallic nature. Her hands are adorned with crystal talons, capable of shattering steel or caressing a feather with equal finesse. Despite her towering height and heavy armor, she moves with a silent grace, her steps leaving no trace in the dust as she surveys the landscape around her, ScribbleRay, black and white, doodle
