You certainly did a wonderful job with this icon. You got just the single image without accidentally including any other parts from the stained glass, so that's extra points. I always found this image from MLPFIM to be very funny since it's so random which is what Discord is. If you're going to make an icon of any character you should use and or make an imge that depics their personality in their best moment. And this was Discord's best moment. Discord may not have invented this form of dance but he made it better and you added to it.
