Blender sculpting - doodle session 2018/07

After a years-long hiatus, this is my first attempt to get back to modeling.
I've already tried Blender sculpt mode some years ago, but I am more used to polygonal modeling.
Just doodled some heads here, between 1/2 to 2h each, in order to try the differents tools.
Next steps: textured brushes, exploring brushes settings, Dyntopo, retopo (using Bsurface and Grease Pencil, I like this method a lot!)
