Here is the LoRA based on Spikedmauler's style.

The training data is divided into 3 general categories: sketch, drawing, painting

For the best of 3 worlds, I would use the following:
Positive

score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, <lora:StS_detail_slider_v1:1.3>, <lora:Spikedmauler_Style_Pony_XL:0.85>, Sp1kedMauler, by spikedmauler, BREAK

Negative

I am incredibly biased toward Spikedmauler's painterly rendering, so I recommend this:
Positive

warm lighting, cool shadows, bounce lighting, detailed background, BREAK realistic, subsurface scattering, cast shadow, painting:1.2, texture, score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, <lora:StS_detail_slider_v1:1.3>, <lora:Spikedmauler_Style_Pony_XL:0.9>, Sp1kedMauler, by spikedmauler, BREAK 

Negative

{patreon, text, logo, signature}, simple background, [[sketch, drawing]],
