This is a LoRA trained to produce character drawings similar in style to that of Bruce Timm's portraitures. Here are a few tips to help get the most out of it:

Model: ponyDiffusionV6XL or similar

CFG: 6

Step size: 20

Resolution: 832x1216 (generating smaller than this may exaggerate compression artifacts)

Upscale: 1.5x upscale factor using ESRGAN_4x sampler with a denoise strength of 0.5 or 0.6. This is a good way to preserve the art style.

Trigger prompts

Negative prompts, to help avoid getting a brown background:

(monochrome, brown background)

Note that it really likes to make the background brown and yellow. Adding monochrome and brown background to negative prompt helps to avoid this, but should also try to specify background color in the prompt. Adding even "white background" to the prompt will also help avoid getting beige backgrounds.

Pony score prompts are somewhat optional. Using them does produce nice images, but they do influence the style slightly. Without them in the image tends to have a slightly flatter 2D look, while using them tends to bring in a little bit more shading. I've been having fun experimenting with both. 

I find it best to keep the prompts short and concise. Long prompts will quickly make the style drift.

Sometimes there are jpeg compression artifacts visible. To avoid this generate high resolutions, use pony score prompts, and upres with a denoise factor of 0.5 or 0.6. For V2 I will hopefully be retraining with the problematic images included.
