I like doing some abstract stuff so I made a lora with my old sd1.5 gens again.
You don't need to use the trigger words for this lora, I just added the keywords that was mainly trained with.
This lora have a lot of bias and have difficulties focusing on humans, so you should reduce the strength a little if you are not able to have a human. Or you can describe them more and move it at the start of the prompt.
You can also use it with low strength to make more colorful background.
