Finished version with all OC's with Tourmaline, Sunstone, and our new mystery comrade, with hair as white as clouds...

*Drumroll please....*

DADADADADADADA!

Moonstone!

Moonstone is a part of Blue Diamond's court and Tourmaline's first friend in the group. Moonstone and Tourmaline both have a connection to Lapis Lazuli...

Yes, Sunstone is actually the leader of the group (even if Moonstone and Tourmaline don't trust her that well).

Hope you guys like my drawing! Now, off to study!
