So you need a tutorial for everything? You can only make a face if you actually know how to model and that applies to hair as well. If you do that tutorial i assure you that you will be able to do the face. Its simple, create polygons matching the face and makes pyramids for spikes. Do you really need a in-depht tutorial for that? Please remember people make tuts for you to LEARN, not to model something you are going to use in your "OWN" cg film.
This is my opinion but a 30 second cg film isn't really that simple and if you are asking people for help on how to make face and hair, how can we help? You are looking at modelling terrain, character rigging, uv mapping, skinning, animations and modelling.
I am not saying you are incapable of it but if you are really prepared to start a cg project then i suggest you be better prepared
