Gus the shiny skull

Meet Gus. When he was alive, he loved shiny things so much he put gold, copper and cobalt onto his teeth. But unfortunatly, the metals crept into his skull, through microfractures (he had a hectic life) . Intoxicated, he lost his skin and was left for dead. But, at night, we can still see a golden shine from his skull... *(This was my first full projet on ZBrush and Sustance, made upon a tutorial by FX Mélard, professor at HEAJ college. So it ain't perfect, there are improvements to do on teeths and retopo)*
