Training a Style LORA Issues...

Cover Picture is from V2 of the yet to be released Demon's Souls Style i'm working on... V3a is coming out decently.
Certainly there aren't many informations on the details or Lora style training, and while i'm trying and learning in the process, things do not seem too easy...
It seems that you need to balance as much as possible the sources you are using, for using too much of a concept may have it spill over during prompts!
i.e. Having too many snowy forest in the dataset may bring the forest into a snowy city prompt!
Things are in any case getting better as far as quality, altought the humans are damn monsters so far... I guess it's due to the scarcity of them in the dataset?
As always any help or suggestions from the experts are super welcome!
