I've been working in computer graphics for about 7+ years now. I first started sculpting with ZBrush since they released version 2.0 some years ago, but off and on. Only recently have I been incorporating it into workflow for just about everything, it's just such an awesome piece of software- no 3D artist should be without it. As for modeling in general, I first began the self taught route back during my modding days with CryEngine and Farcry for the PC. Those were some good old days, not a care in the world and working in 3dsMax till 3 in the morning just having fun creating new weapons for mods and stuff.
