anyone got solid guidelines on what you can get away with on tinting lineart/shadows? i had a friend with super cool skin/accent in trickmurk that didnt make it to winning circle and im pretty sure it's because it was rulebreaking on that front but i don't have evidence to show my friend

(yes yes could be other reasons too but there was big interest so he's gonna print it and I dont want him being hit with rejection right out the skin queue you know?)
