v1.0 - Bart Simpson, both young and adult versions are trained. You can add some facial hair to him if you want.
Here are some prompts I used while training.
"bart Simpson, adult bart,young bart, yellow skin, blonde hair, black eyes, other hairstyle, brushed hair, stubble, mustache, facial hair, earrings, jewelry, flat color, parody"
v2BetterRes - please avoid score tags because they mess up the eyes. Also try to include yellow skin tag so he isn't mistaken by a furry. He can have slightly different hairstyles if you include or exclude spiked hair tag.
