Main prompt tags: zummigummixl, anthro, bear, glasses, pince-nez, hat with feather, blue tunic, red cape, gold medallion <----------- should always be included

Style control:

• for the retro TV show style add following positive prompts: cartoon, toony, retro

• to avoid the retro cartoon style put cartoon, toony, retro into negative prompt

• for mixed style only put cartoon into positive prompt

Prompt tips (green - positive, red - negative:
- purple bear if his fur changes to brown
- glasses, pince-nez, blue tunic, red cape, hat with feather, gold medallion, sash - full clothing
- hat, glasses, pince-nez into negatives to remove the hat/glasses (or just remove from positives)
- black eyes will help reinforce cartoon style since Illustrious likes giving him detailed purple eyes
- wrinkles, mature if you want Zummi to appear older (but still canon)
- 4 fingers can help to get the canonical version of Gummi hands
- (pince-nez:1.1) in case you need to reinforce his glasses
- golden medallion with g helps with his Gummi medallion depiction - Illustrious does not like his medallion - it will often look too detailed or change letters, becomes worse with higher CFG/steps. No easy fix unfortunately

The LoRa should support all kinds of Illustrious checkpoints. Tested working well with the following:

• Nova Furry XL v5.0

• WAI-NSFW-illustrious-SDXL v12.0

To improve details:
- generate using higher base resolution (e.g. 1216x1216) or use latent upscaling / highres fix - especially when trying to do full body poses
- for fixing wonky face/eyes I use FaceDetailer node (comfyui) + Adetailer Face finder model
