1 - Use model called YiffyMix 3.1 or 3.2 - they are the mix of Fluffyrock for most of the furry stuff + some of F222 for women bodies + other HD models -> therefore resulting in more anthro-ish figures leaning to realism.
2 - Also download embeddings named dfc, ubbp, updn, bwu, boring_e621_v4, and probably some others.
3 - use this prompt AFTER everything - (masterpiece, best quality, ultra realistic, 4k, 2k, (intricate:1.1), (high detail:1.3), film photography, soft focus, RAW photo, photorealistic, analog style, subsurface scattering, photorealism, absurd res:1.1) - you also may use keyword BREAK before all that, if you use Automatic1111
4 - the prompt itself is a free wording/tags, such as solo (anthro female SPECIES:1.2), lying, on back, pregnant, huge breasts, lactating, hands on belly + some keywords for background, such as detailed background, bedroom, bed, pillow, balloons, carpet
5 - use Hi-Res fix, especially good with 4x-UltraSharp upscaler beforehand.
Ta-da! You are golden!
