I tried character modelling and i find it to be very difficult and time consuming. Your work on that head is very impressive. What modelling technique did you use for that?
Yes it is indeed very difficult and time consuming. It sometimes takes a whole evening just to make a proper ear or nose. But fortunately, I goes better and faster which each time, so hopefully, in a few years time, I'll be able to do this within a day or so, instead of a whole week.

Anyway, for this model I used point-by-point modeling (with a background image as reference).
