Model based off the lemon/orange pfp guy (sos/sosforsource)

The model is kinda iffy, since the base model style would often bleed into the Lora instead of the Lora creating its style

activation tag : "sosforsourcestyle"

My recommendation

You should start with : "sosforsourcestyle, rough_sketch, sketch" in your prompt
"monochrome" tag is also sometimes good

for negative prompt : "censor, flat colours"
