For 1.5: Depending on the checkpoint model, her eyes might turn out blue, so I'd recommend throwing in "blue eyes" in the negative prompt or the adetailer extension negative prompt. Recommended weight should be between 0.65 and 0.8, trigger word is skyeparkin

For PonyXL: Recommended weight should be between 0.7 and 0.8, however, if you're going to prompt her with her casual outfit (blue jacket, hoodie and black pants), I'd recommend lowering the weight between 0.6 and 0.7, and using 3D in the negative.
