Surprise, Parka Posy was a changling all along!
 
I decided to revisit Parka Posy as an independent character, rather than a representation of myself, although she still carries many aspects of me.  
I’ve changed her eye shape, but other wise her unicorn form has stayed the same.  
I like to imagine she’s some kind of Fae creature from earth that took the form of a changling once stepping through the mirror into Equestria. Probably masqueraded as a unicorn for a long time since she preferred the pony environment more than the hive environment (at the time)
