Using "SeekArtMega" model as a base because it's already fine tuned, more generic and less biased than other models, they also fixed many missing artists: https://civitai.com/models/1315/seekart-mega

As the papers mentions "100 steps should be fine for subjects, otherwise 300 for styles" : https://arxiv.org/pdf/2208.12242.pdf

Some say to multiply your learning rate by ( Gradient steps * Batch size ), however, I never achieved good results, thus, I usually do ( "0.000001" * batch size ) and go even further with polynomial decaying curve: https://huggingface.co/blog/dreambooth

I used these packs of regularization images to nearly cover all of the "subjects" around "costume design" and "character design": https://huggingface.co/datasets/ProGamerGov/StableDiffusion-v1-5-Regularization-Images

And according to the papers I set the regularization images per instance images equals to the amount of epochs they are going to loop through: https://huggingface.co/docs/diffusers/training/dreambooth#training-with-a-priorpreserving-loss

Try as much as possible to avoid color patterns, because they will reflect in your final trained model ( used shutterstock tool for extraction: https://www.shutterstock.com/pt/colors/color-palette-generator )
New model released on civitai : https://civitai.com/models/7105/cocept-costume-designer
Focusing costume design and character design, with bias towards oriental games costume design.
Model generated through 4 stacked dreambooth sessions using Seek Art Mega for base model and sucessive fixes : https://civitai.com/models/1315/seekart-mega
