Here, I think I made a template worth sharing.

Positive:

score_9, score_8_up, score_7_up, score_6_up, source_pony, rating_safe, solo, (feral twilight sparkle waving hoof at viewer), unicorn, happy, looking_at_viewer, purple glowing horn, ponyville, cloudy_sky, detailed_background, (zPDXL:1.8), [dimly lit, night, dark : climatic_lighting : 0.1]

That last part changes the tags mid generation by the percentage of the decimal at the end. Starting off with dark / night / dim lighting then switching allows for deeper blacks / more vivid colors.

Negative:
censored, (zPDXL-neg:1.8), (missing limbs, extra hooves, text, weird colors, 3d, bad art, poorly drawn, disfigured, deformed, extra limbs, ugly, worst_quality, low_quality, lowres, blurry, out-of-focus, wrong details:1.5), normal_quality, source_filmmaker, watercolor_\(medium\), score_4, score_5, score_6, puffy_lips, sketch

CFG here is 4. Use low CFG for first pass then like 5-7 for 2nd pass for sharper details on DPO model.

Seed: 892065376
Sampler: DPM 2M Karras
Steps: 24 (you can use more for 2/3rd passes)
First-pass res: 1344X768

For how/what to download to run the model yourself (forge through stability matrix imo) and other help / links to helpful resources there is a AI Art thread on /MLP/

Btw, for anyone who wants more pony I post a ton of my “doodles” / experiments here and I’ll continue to do so:
