This model is to create the pouty look that is hard to get on most Pony/SDXL models. Specifically, the trifecta:

Pouty bottom lip ✅

Furrowed brow ✅

Chin quiver ✅

In addition to providing a pouty/miserable expression, it bumps the model over to the "realistic" side of styling fairly quickly. This initial version is slightly overbaked so it can be used at lower activations, so I expect it to play nice with other LoRAs. In any case, there isn't much to say other than that.
