New model this one was trained on only images from the anime so the style it's really baked in, if you want to mix it with another style/clothing please use it around 0.5 , for a nything else use it at 0.8, i tried to do a Gear/casual lora but the Gear on this one it's a little off, so if you want to generate her Gear look please use this one instead:
