Aesthetic Quality Modifiers - Masterpiece

Training data is a subset of all my manually rated datasets with the quality/aesthetic modifiers, including only the masterpiece tagged images.

ℹ️ LoRA work best when applied to the base models on which they are trained. Please read the About This Version on the appropriate base models, trigger usage, and workflow/training information.

Version 5.0 [anima-preview-3] (Latest)

(Temporarily including here as the "About This Version" section is having issues)

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 .
