Due to a lack of resources recently, there's not much that can be done on the pony side.
I tried following the trend of fine-tuning the IllustriousXL.
Since I'm not very familiar with SDXL, I didn't make too many adjustments.
Of course, I focused the adjustments on NSFW content.
Base: IllustriousXL
Since the adjustments were minimal, the artists and characters available in the base model can still be used directly.
