This next drawing is from the other campaign I'm in (technically finished, awaiting part 2), Tomb of Annihilation.

This is my precious baby Grilu; a telepathic extraplanar horror imprisioned in a lake within a death tomb, who has since gone wildly insane. She enjoys playing catch, and making her victims immortal before completely subjugating their minds and bodies for all eternity.

I love her.
