You can try any model you want, however I really suggest using Hassaku XL Checkpoint.
Important note: This is a fine-tuned version (Or at least my best try), however more often than not, the outcome is aged down. I'm completely oblivious of why this happens, but a workaround I found is using an age slider.
I'm still unsure if I should upload it or not, but I'm sharing it in case someone might just not care about the inconveniences.
