As amateurish as I am I have actually with help from what I have seen others do, and some AI managed to create a workflow that tests loras. In my case I needed a tester for a few KREA2 loras I made. Since all my help has come from this place I want to share back what I can. So if anybody finds it useful I will be glad.

I use some real simple prompts to test a lora, to then filter out which loras are best. For instance:

I start with a simple prompt that alters the lora as least as possible:

"photo portrait of [your character], cinematic lighting, natural skin texture"

Then I change the pose and add some changes to the lora:

"photo portrait of [your character], ice blue eyes and red glossy lipstick, widely open mouth, looking partly up to the left, cinematic lighting, natural skin texture"

I do this until I have filtered out unecessary loras.

Good luck and let me know if it works for you or you have ideas to improve it.
