Stranger head topology study.

Doing a new character here. Few hours of work there already. Most of the time has been used to try different shapes, this should be one of my main characters in the future so I'll spend some time on this.

Some explanations for the coloured areas:
Main head loops and cuts.
Detail loops.
Special cuts and dividers/areas of interest.
triangles. (Should usually be avoided if possible) (Edit: forgot to add the red triangles on the model there, there are a few)

Doing it in Blender. [link]

EDIT 01: Edited topology on the ears, mouth area working properly and actually looks like something already.
