I am quite confident that your Art has not been used for training in the particular model. But of course I cannot be 100% sure as a stable diffusion model is not a collection of images.

Technically it would be possible to train an existing model on your Art by creating a Lora model which functions like a patch on top of an existing model which forces the output in the direction of your art style.

Recently it would also be possible via a model called Clipvision to feed images from you into the generation process to get a result that is similar to your artwork.

Then we have image to image which would use a existing image from you as base in the generation process.

Lastly controlnet which would read among more things character poses from your images.

All of this is not h the case here. As charming as your character is, I had it not in my mind when generating this picture.

Also I definitely see myself not as an artist. You are an artist doing creative work. This is just a technical hobby for me to heat my office room with my graphic card .
