The designs on the time & space girls are disgustingly intelligent.
The nods to dialga and palkia respectively were subtle enough that I had to triple take to catch them all.
I like how they don't scream "LOL WE REP LEGENDARIES" in a childish way - a pitfall that many OCs fall into (like the insurgence cults).
Their pose is also mad unique. Space girl especially looks ready to dance, but her face says "I hate dancing with you" LOL
