Skirks uses the same sword holding stance as Keqing, Lumine, Furina, Layla, Nilou, Ayaka, etc etc. She's not a "hag" and doesn't use the hag model, even her run and walking animations are the same as the female characters I just mentioned. Doesn't matter what you think, what matters is what exists and Mihoyo used the Fischl/Noelle/Amber/Sucrose body model to base her off. Just because she's taller doesn't make her the same as Jean, Raiden, Yelan, Mavuika, etc. That's like saying Varesa doesn't share the same body model type as Mualani because she has giant tits and thick thighs
