First time training a style lora, not exactly sure about a lot of parameters so there's bound to be more than one error. Having said that, this LoRA its supposed to give 1girl prompts a rich abstract background based on the works of Gustav Klimt plus some other works that were also based off his works. I've tried its compatibility with other pony character LoRAs of my own and it works so far, though I cannot guarantee compatibility with the vast amount of LoRAs out there nor how it would work with male characters LoRAs. While I would suggest to copy the same prompt structure found in my prompt samples to get similar consistent results, you're more than welcome to experiment with different prompts to test the versatility of the model.
The trigger word is gustavklimt, however I suggest also having "traditional media, abstract background, painting \(medium\)," thrown in the prompt, LoRA weight should be about 0.8 up to 0.95 depending on what LoRA you use it on.
