Nice! I was thinking a good EG would be this.

EG;

She lifts a small chunk of earth and summons water as well, they collide and a mud of sorts starts to form. The mud encases the victims head and turns to a form of hard stone. The water that is now left out becomes spikes and impales everything inside of the stone mask.
