This is the V1 model of the Lexica art style.
Trained on the Lexica Aperture V2 engine art style, which had a unique 'gold'/ non realistic look.
You'll find characters have long necks (especially female characters), on comparing this, I saw the original Lexica images had the same stylization, so it's something that the art style does.
Use the trigger words Lexica Art Style with this Lora. 1.0 will overpower the image, 0.6-0.9 will give great results.
