This model is a blend of two different style LoRAs that I frequently use. I am still testing out the use case quality and stability, but here are some general guidelines:
You can have this style weighted higher than the other LoRAs. I found good success between 0.8 and 1.2 based on the prompt.
Similar to above, the strength of the LoRA is also dependent on the Checkpoint that you use.
The text "vivid colors" in the prompt tends to make the style more pronounced.
