Low poly!

Going low poly this time. So I'm looking up some images of low poly faces. I always start from the head first when modelling a character. While trying to model low poly I'm also trying to ensure the topology follows the anatomy from the face. 

Looking at some of these references I like how the lips have been approached. I don't know if I'm gonna give him any nose holes though. I'll only do it if the director wants me to but no ones gonna observe that much detail.

My first step of modelling is just laying out the topology and work with the edge extrusion technique.
Face is going to be animated so this approach is best for me.
