Ultramerine Rhino tank

Hi, my name is Michael Darwent and I am an undergraduate at Wirral Metropolitan College studying Illustration with Animation. I am extremely passionate about video games and aspire to be a 3D asset sculptor in the games industry. I have recently started to learn Maya and Mudbox and decided to make a Space Marine Rhino tank. I've still got a little bit to do to finish this, but here it is so far! to make the Ultramarine emblem I created a skull in Mudbox and imported it into Maya.
