Wow, this thread came back…
In the past, I've modeled any heads I made with the point by point method. I've always thought it was the most intuitive of the modeling methods since you could control your poly flow very easily.
Anyway, I think it's best to learn all the different methods as it can only help you become a better modeler. I've never been able to understand how people could take a box and make anything resembling well....anything.
But lately, and especially after seeing some of the work done in Mirai by Raitt and Krol, I decided it was time to try again and learn box modeling. I think considering some of my early attempts (pretty sad actually), I'm doing ok.
