Nella, by sssonic2.

The sweet spot seems to be either 0.7 and 0.8.

In general, this setup works for me:
positive

<lora:Nella_sssonic2:0.8>, n3lla, furry sloth:1.2, long sloth claws, blue hair, grey fur, grey body, markings, curvy, slightly chubby, big breasts, wide hips, huge female, 

negative

monochrome, grayscale, human
