The images i am showing here are generated using an updated workflow. you can call it as v2 of my 4 stage workflow from the above link. the new one is tuned to work well with other lora's and controlnet but prompt adherence takes a little hit. its still WIP. i will post it once its ready. until then just experiment with EasyCache node and Latent upscale

Sydney Sweeney sitting near a window in soft light

<think> This name evokes a modern, urban identity with Middle Eastern-European heritage. Likely minimalistic fashion, academic-creative profession, poised posture. </think> <think> 这个名字带有中东与欧洲的混血背景，给人一种优雅、沉静但不浮夸的气质。结合她是建筑系学生，可以推测她穿着简洁、注重线条比例。 </think> <think> She's sitting on a cushioned bench near a wooden panel wall. There's a marble café table nearby. Compositionally, she's placed in warm directional lighting. </think> <think> 她坐在一个靠窗的沙发位上，背景是一面深棕色的墙体和木质护墙板。自然光从右侧窗户洒入，勾勒出她面部和肩颈的轮廓。 </think> <think> Her skin is very light with neutral-warm undertones, catching golden side light. Hair is dark brown, long, softly curled at the ends. No bangs. </think> <think> 她的肤色非常白皙，偏暖调，在阳光下带有微微的金色反射。头发是深棕色，自然下垂，没有刘海，发尾略微弯曲。 </think> <think> Outfit: sleeveless black halter top, high-waisted beige mini skirt. Fitted but elegant.
