For eyes I just do three quick brush strokes (as shown by the red)
noses are made out of a bunch of small triangles. I first draw a slightly curved stroke connecting to the eyebrow and follow it with a small triangle at the base of the nose (used to show other side of nose. this bit is not always going to be visable keep that in mind) and a small notch (the nostral)
(the only method I have for drawing lips is to do the top lip first it’s sort of a freehand thing from that point on sorry ;o;)
the first couple of pictures are just to show you were everything is on the face
