Drawing practise: Faces

I am still trying to brush up my drawing skills. Right now I try to capture people of a wide range of ages, genders and ethnicities.

These are my latest exercises.

All done from photo reference:

#1: Walter Herrmann, own photography

Thanks to AngieStock for the beautifull reference of #2: Apple to be or not to be

#3 shows  Idris Elba
