/3/ - 3DCG

I want to make a model but I don't know how to best go about it, I saw this video https://www.youtube.com/watch?v=0QT1GNMevfc on a interesting way to do it, but I'm unsure of how to best get the faces to contour to the design like I want, is it a good way to go about model creation? Or should I try sculpting it instead? How do you go about the process?
