recently asked if I had ever finished my Luna-- well, I did. Mostly. Here's a pic, next to the Target Princess Luna. I like mine a bit better, but I couldn't help but buy the one from Target. It helps she came with a molded Pinklestia that I can and have butchered in the name of science and brushable ponies everywhere.
Hands down, you have one of the cutest and most accurate Lunas I've seen. When I look at her, I can just hear her politely saying "But, your Princess commands you! Would this face lie to you?"
I love Spike face-planting in the back ground and I love your Derpy, I'm currently working on a Derpy Custom, which may go up for sale on ebay when it's done
