Another update, and this one didn't take nearly a year! Sensational! This new version is trained on Pony Diffusion v6, using pretty much the same dataset as V2. PDXL already knows what Penny looks like, but not her clothes. That probably makes about half the dataset redundant, but whatever, it works.
Illustrious update! Illustrious already knows Penny's first design pretty well, so I piggybacked off that. However, that also interferes with her second design, so it has its own tag now.
