This Lora is quite special. Let me explain: many years ago, I used to create illustrations for all my NPC's in a homemade RPG using a web app called BeFunky. It could apply a "sketch" effect, which, in reality, simply reduced some details and added a pencil cross effect.
Today, I've utilized this effect on over 300 NPC images to create this style (yes, I'm quite addicted to creating RPG characters).
In practice, I find that Lora works better with shorter prompts. For a more striking effect, use black and white pictures (add 'black and white' to your prompt and don't use any colors or add "colors" in you negatives). You can use it with 1 or more (like 1.5) for more effect.
I don't believe this Lora will be a revolution, but I had a lot of fun creating it (it's my second one), and I hope you will too!
