Hey this isn't necessarily an idea but it seemed fun to bring up. Try and find funny little ticks in the game from a visual standpoint.
Here I'll start: 1) Every school classroom has windows except the ice school! 2) Tu Luk Kwo, a goat in MooShu, has a weird square at the end of his braided beard. This is unlike all the other tips of the goat monks' braided beards.
I know those are random, but they're fun to look for!
