Use this checkpoint and everything comes out like scribbled with charcoal. No LoRA and no keywords needed. Just prompt your image and enjoy the style. Very good at portraits, but also nice for everything else and it does respond to upscaling very very well :).
Of course avoid keywords like 'cinematic' and similar ones in your positive prompt part. If that is not possible, you can aid the style with words like 'thin lines', 'bold strokes' or even 'scribble' if you get something too photorealistic.
I recommend 'Euler(a)' as a first sampler to play around with this cp.
