Hi, I'm trying to learn how to create characters, such has human, monster, etc. and then planning to animate them later but i don't know what's the best process to follow

right now i am modeling each of my characters' body part individually in NURBs, then I convert it to Polygons and stitch it together, then i covert the whole body of character (once all stiched together) into sudivision....

If I want to animate these characters, is this the method in creating one?
thanks
