Headspace Aubrey ヘッドスペース・オーブリー - Omori オモリ

The headspace version of Aubrey from Omori.

The result of my experiment with Lion optimizer. unet lr = 1e-5, text encoder lr = 5e-6, epochs = 20, weight decay = 0.01, betas = (0.95,0.98).

Results Summary

Perfectly usable at weight 1. Usable at weight range [0.9, 1]. Anything lower may diverge too much from the Lora.

For her usual appearance, use

prompt: aubreyheadspace, 1girl, shirt, short sleeves, hair bow, smile.

Stylized checkpoint models (Counterfeit, Pastel-Mix, etc.) seem to be hellbent on adding shorts/trousers on Aubrey. Idk if it's my dataset's fault for not including much pictures of her bottom-half view or whatever.

This could be helped by increasing the CFG scale to 10 and adding

prompt: bottomless

and/or

negative prompt: shorts, trousers

It may also help to replace the prompt "shirt" to "dress". (Is she even wearing a dress? Idk)

EasyNegative is recommended, quite compatible with other non-character Loras.

Though there's still (very) much room for improvement, the Lora itself is pretty decent.
