(dupe for merge)
 
I based this on this nice vector: http://moongazeponies.deviantart.com/art/Queen-Chrysalis-337526355
 
Its kind of art for the story Im writing. I wanted to saw how Pinkie could look like a changeling queen.
 
Queen Metamorphosis.
 
Queen of parties in Ponyville, disguised as normal (well, we are talking about Pinkie Pie normal) earth pony.
 
Why she is so different from other changelings?
 
Because she is well-fed. Hungry changeling slowly loses his hue, when he finally reaches black, and then he dies. Same goes for holes. More holes, more chaotic places starving or ill.
