Started with 2d graphics design while i was still at school, started with 3d around 3 years ago, took atleast a year to start producing anything resembling quality and another year and a half on top of that to start making stuff people would consider paying for, doesn't sound like a lot of time, and relatively speaking its not but that times been spent craming as much modelling practice and techniques into my spare time as possible, still loads to learn but know enough now to be offerd some fairly big jobs and recommendations.
