This LORA generates high detail quality moss as well as sticks, leaves, and Forrest images. Try "dead wood" for images of one specific log, not much variety on that. Use "mushroom" for equally meh results. But use "moss", "moss2" & "spiky moss" with either "distant landscape" or "full landscape" for best results. This LORA does odd things on occasion so don't expect consistent results. Especially on a non-realistic checkpoint.
I made this model using pictures of moss, try:
Moss
Moss2
Spiky moss
sticks
distant landscape
full landscape
tilt shift
forest background
Negative prompt:
blurry, blurry background, tilt shift (if you want)
