The block out pass in Zbrush.One big mesh in dynamesh.
Then some refine, separated all piece by masking then, Close holes, dynamesh again and cleaning, adjust the shape, detailling for each piece. Mainly inspired by Michael Pavlovich workflow except i didn't retopologized for cleanning my shapes, it's all sculpting. Only the hands , claws and cylinders are made with subdiv modeling.
Congrats to all contest participant, this challenge was really fun
