This Lora is used to generate car sketches. I hope to train a completely black background, but the generated image contains paper and pen, which looks like it was drawn on paper. This is not what I expected, but it may be useful.You don't need to use a pen in the prompt word, it has a certain chance of being generated. A weight of 0.7-0.9 is better. You can use angle and vehicle type in the prompt words.
I need to emphasize that you can use it for inspiration, but you must not deceive your teacher with it, saying it was hand-painted by you. Your teacher will recognize and dismiss you.
