This is an Illustrious lora for a Christmas Town style exterior architecture design. I was between having this as an architecture style lora and a background lora. In the end I choose the architecture one since a Christmas Town is a town that did some exterior architectural design to decorate for Christmas, and is not always decorated as such all year long. Since it involves exterior design, I decided it fits more as an architecture lora.
A weight of 0.85 to 1.25 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 3 to 7 with most working at around 5.
Prompts for V1 of this lora are ( ChristmasTown, architecture, Christmas, ).
