ay I present my updated style!! I have been really inspired recently to draw Luna, cause she is one of my favorite ponies.  
I wanted to change her up a bit but not much cause I already really like her design.  
So this is kinda like a reference so I didn’t shade this either.
 
I wanted to give her a more royal and elegant appearance.  
I gave her feathers on her legs and face, cloven hooves, and long fur feathering on her legs to better represent the three pony types (Earth, pegasi, and unicorns)
 
I will probably base her soon so I can have a show accurate version as well.  
Not to mention I need to draw her with all her royal accessories.  
Eventually I’ll also draw Celestia (who I imagine to be a queen rather than a princess, like Luna)
