Aesthetic Quality Modifiers - Masterpiece (Anima)

Trained on Anima Preview-3-base

Assume that any lora trained on the preview version won't work well on the final version.

Recommended prompt structure:

Positive prompt (quality tags at the start of prompt):

masterpiece, best quality, very aesthetic, {{tags}}, {{natural language}}

Updated dataset of 386 images, all masterpiece tagged images trained in Kirazuri (Anima) model version 2 dataset.

Trained at 1024 x 1024, 1280 x 1280, and 1536 x 1024 resolutions.

Previews are mostly generated at 1536 x 1024 or 1024 x 1536 .
