Precious Metal Reference

I have commissioned some artists for a reference of Precious Metal, but I wanted to try my hand at one too ^^
Precious Metal is my ponysona. Her talent is alchemy/engineering. She has a little Luumie named Gadget that helps her at work and collects gears, which she places in the fur of her ears and tail. Precious is optimistic, curious and happy. She has a small group of close friends, including her Special Somepony, Heavy Metal. Her cutie mark is a heart with gears and wings.

Luumies are a closed species by
