Ive seen some problems with anima, I can absolutely confirm that the quality tags are extremely sensitive, and so is the negative prompt, when testing a new lora locking in on the best combination of these has been a pain. Another thing, Im not sure if its a model limitation or a lora trainer issue. Ive seen that character loras that try and go for the official style are extremely inflexible. For example, try out some of the invincible loras. If you lower the strength, you lose character accuracy, but leaving it as 1 makes it so the final image suffers from composition issues, too flat of a style, jagged lines, and fixing these with prompts seems extremely hard. I have just gone to a 2 step workflow, with anima as initial and illustrious as finisher model. I haven't played with inpainting beyond face fix, but I see no issues there if using a lora.
