Gemsona: Onyx 2.0

Concept doodle for a new redesign for Onyx. I missed drawing my grumpy gem robot

behold her GIANT DUMB ROBO HIPS

to refresh, Onyx is a gem from Homeworld that's been robotically augmented to better serve her superiors. She is a technician gem and her purpose is repair and maintenance of gem tech
then she crash landed on Earth and was left to essentially rot so she's bitter as hell
super intelligent and super grumpy, Onyx is the brains (kinda) in Team CLEO (Citrine, Larimar, Emerald, Onyx)
