I completed this a few months ago, but this is my very first completed pony custom! Her name is Midna Tavers, and she’s property of a friend of mine.
 
She was based on a Crystal Empire-era Rainbow Dash, and was painted with (cheap) acrylic paint. Her mane and tail were sculpted with Super Sculpey, and unfortunately a couple bits off the tips of her mane broke off just after baking them. She was sealed with Satin Mod Podge.
 
In the future I’ll probably work a little harder to keep the sculpted parts smooth. Not a fan of how lumpy they look close-up. But for a first custom, I think it’s alright.
