Persephanii (Stephanie Nelson) is an American model.
Training includes, well, a lot of cleavage. Can get nsfw. You may want to use "(nude:2)" or something similar as a negative prompt.
She is known as the "thick yonce". You could experiment with keyword blending to tweak her facial features (e.g. "[p3rs3phan11:Beyoncé:0.9]"). Other ways to tweak her look include the Hyperbreast LoRa and the Gigantomastia Hypernetwork.
Under some setups, this embedding can create a glaring color scheme. This can usually be fixed, though, (for example, with epi_noiseoffset). She likes to wear blue by default.
See more pictures of her on my DeviantArt page.
