Aurora was made to counterbalance the realism that Euclid provided, giving you a model that can go from creating cartoons to anime and even creating semi-realistic images. As you can see from the preview image it does have a lot more freedom and artistic expression than Euclid. So please enjoy and have fun.
V3 Chroma does the complete opposite of Lumina, instead of bright, bold colours with more going on, Chroma has less vivid colours and a more drawn/painted aesthetic. It would be perfect for those who like to create D&D characters to print out.
