EVA-Beatrice from Umineko fucked in the position from the second image;
For her outfit i'd like her to wear nothing besides the hat, gloves, shoulder piece, boots
Shoulder piece would probably partially cover her left boob (where the arm's down) for the under/sideboob and would wouldn't be in the way of her lifted arm (make the armpit and boob visible)
have her one leg and arm tied at the top with the red web she uses in the VN (i can send you an image if you want but it's basically just red string)
(dunno if that'd look awkward, seeing how it isn't visible in the 2nd attachment, if it looks weird just put it offscreen)
Heart pupil are welcome
Oh and please make her eye color purple (it's blue in the vn and purple in the anime, purple's just kinda hotter)
Please contact me if you have any questions uwu
