During production, I did bunch of early statue exploration sketches. Once things were locked down a bit, I was asked to digitally sculpt the statues for the Italy set. (The scene where Arthur and Mera look through the bottle, then Black Manta shows up with some Atlantean goons) .Then the final Zbrush models were sent to be router cut from foam. From there, the talented sculptors used these as a base to work over.
