wow... those are some good advice. most of the time when i sketch a face i just can't get it right. the face doesn't look like the real one. i guess my measuring skill is not so good. i see a picture in my phone and try to draw that but the face gets bigger or eyes don't match or the lip is too short, this kind of problems happens. your sketches are really great. can you make a post about measuring? i think that would help a lot.
