so this is just what I imagine some of the My Little Pony Royalty to look like  
this is my next gen universe / headcannon?  
im sure others have similar ideas
 
first, i would like to say that I imagine them all to have more intricate armor?  
i dunno it was just fun to add
 
Cadence:  
I never understood why she didnt keep her crystal pony look because isnt she the ruler of that kingdom? I think its suiting to appear crystal, the same as her subjects
 
Luna:  
I just like the thought of Luna looking kind of like a bat pony mix with a normal alicorn
 
Celestia:  
Okay, so, Ive always had a big problem with Celestia`s design because, her colors never really stroke me as ‘Princess of the Sun’. So I changed that by a lot because it personally just bugged me but I know everyone has their opinions
 
Chrysalis:  
This is more for my next gen universe, where Celestia and Chrysalis are married and Chrysalis become reformed. Tried to mix in what the reformed changelings look like.
