This is Valmina Dia Nox from the anime "Iya na Kao sare nagara Opantsu Misete Moraitai Returns", episode 2. Images were generated at 896x1152 with euler_a, simple, 30 steps, 4.0 cfg with anima preview 3 base. 1536x1536 is also possible, just takes longer.
I also use these loras at 1.0 strength:
Aesthetic Quality Modifiers - Masterpiece
Anima Highres Aesthetic Boost
Basic character tags:
V4lm1na, pink eyes, horns, purple hair, pointy ears, small breasts,

heart-shaped pupils, fang,
Clothing tags:
dress, cape, garter straps, bridal gauntlets, thighhighs,
