Original Description:
 
this is my first take on Make your marks/ the G5 series Main Antagonist.
 
I used a Nightmare Moon base but alter the legs to match her accurate height in the show along with changing her wings to look more like her actual wings, and I noticed that Opaline has a curved horn unlike any standard unicorn/ alicorn horn so I used King Sombra’s horn for reference and gave it some details. Her hooves guard are just added on by looking up reference and I gave her proper eyes as she doesn’t have eyes slit eyes like Nightmare Moon or Day Breaker as most people think Opaline is a evil version of Princess Flurry Heart which she is not. also her Cutie mark is found on Derpibooru
 
nothing I have to share as hope you Guys like my G4 version of Opaline, even though she is a Despicable character and the worst Mother figure to Misty.
