this Illustrous style lora was used originally in StableDiffusion , able to stabilize the hatching a bit, using double Lora at 0.6 and a mix of 0.3 of Marvel vs. Capcom 2: New Age of Heroes (Style) - V1 | Illustrious LoRA | Civitai

after that i recommend to inpaint the eyes, in the example of the images im working with an inpaint of 800x800 pixeles seem to work fine, this workflow should be like what you would get from the website generations.

Currently testing results on ConfyUI, it will make better results, but in my personal experience ConfyUI tends to leave out the loras involved and gives different results to what you would expect from a default generation
