My first attempt at making a LyCORIS model for Belldandy using Pony XL.
Given that this is based on Pony Diffusion v6 during the training, it's only giving the intended results with base models (or checkpoints) that are compatible with it. Anything using SDXL as a baseline doesn't work at all, or at the very least the results are pretty off.
The facial markings and the rest of Belldandy's facial features are all included in the "Belldandy" tag, so no extra description is necessary. Adding them on top of that tag is going to mess them up, either their shape or color. Her outfits aren't included of course. While I could've trained the model to just make her official goddess dress, I find this very restrictive when it comes to generating other outfits.

For her outfit you can try "goddess dress" and in some cases "golden trim" although the latter isn't always necessary. I should note that I didn't train the model to explicitly make her official goddess outfit, so it won't be perfect. On the other hand, this model is more flexible and handles more outfits without serious problems.
Use "ponytail" to make sure that she's generated with her default ponytail. I tried not to have that built in like previous models of mine, since I wanted to make her model a bit more flexible. It's not always necessary, as there's a strong bias in the training data to have Belldandy with a ponytail, regardless of whether she's prompted with "ponytail" or not.
