Have been doing the orc head tutorial, and it seems to go really well up untill i convert to polygons. Before converting I have a base which is looking for me is looking good. I then change to polygons and my results always seem very different to Kurts, then changing to Sub D where kurts is smooth mine is still very jaggedy further away from what i had at the nurbs stage.

I know I am a beginner, and Kurt is 3d god. But am i doing anything wrong?
