This locon:
Adds contrast
Makes colors more vibrant
Adds details, including background details
Improves costumes
Works fine with landscapes or portraits
Doesn't mess with your overall style, whether it's cartoon, photorealistic, or whatever
Plays well with other locons, loras, etc.
Looks good when weighted at 1.0, and can be really dramatic at 1.5 to 2. The trigger words are helpful but not necessary.
This as created using the amazing conceptmod by @ntc, running for 600 iterations with a prompt of "#:0.1|~beautiful, elegant, confident". I exported the locon a number of different ways, and this one seems to be a reasonable size while preserving fine detail. See the conceptmod tutorial for details.
