Where did you find them? Do you have the original png files? Those ones don't have the metadata you need to get an easy route to copying / cloning them
Interrogating the image though gives us this for the prompt that maybe you can use in a number of different Civitai models to see which fits best:
a sexy woman in a blue costume posing for a picture, hyper-detailed and realistic, fantasy dungeon, plus size woman, doll, hyper-realistic lighting, dark golden hair, featured on amiami, trending on artstartion, real-life big mom, blue skintight closed longcoat, ellora
--
Refining that with a bit of trial and error (we can do this better if we keep going), we can have this:
Positive: (masterpiece:1.2), (best quality), (intricate details:1.2), (photorealism), wallpaper 8k, a beautiful woman, wearing sexy revealing detailed dress, hyper-detailed, fantasy ornate castle window view, cleavage, wide hips, large breasts, sexy cloak, necklace ornament, (sheen to her skin), vibrant colors, (dynamic lighting:1.3), (vibrant cinematic lighting:1.3), (glowing lights and effects and lamps:1.2), lustrous golden hair, realistic skin, smiling, looking at viewer, facing front <lora:hipoly3DModelLora_v10:0.6>
Negative: poor quality, mutant hands, ugly, blurry, low quality, bad-artist, EasyNegative, facing front, boring, dull
--
That gives us something like the attachment - which we can see needs more lighting, and more colors... so you just keep adding to that in the prompt until you get something you need. If you have stable diffusion / automatic1111 - just throw the png into the png info tab and you'll get all the generation details.
