I have created a portfolio with two concepts.
The first portfolio is a cinematic video made mainly of a creature called White Ape from the movie John Carter.
The second portfolio is a Si-Fi-style hard surface modeling portfolio, in which the spaceship Gladiator from the game Star Citizen is the main one.
The first portfolio was created to lay the groundwork for Zbrush, Mari and Xgen.
The second portfolio was created to train hard surface modeling in Maya.
