Answer: ok so this is a bit easier than you think
Explanation: first draw a circle, then split it into 4 (draw 2 linens, one going top to bottom, the other going side to side) after that the line going up and down draw that line a tad bit out of the circle (that's your chin line.) then draw the chin from the bottom of the circle to your line (remember: female chins are pointy and their faces are smaller and rounder, males have long faces and broad chins) after that draw the ears (female: rounder smaller. male: bigger, longer.) then draw a line over the ears this is your eye line, (your eyes can look however you want but do remember guys eyes are typically smaller than girls eyes) noses are simple usually just a small line will work for females, and for males a longer line and some tiny lines for nostrils. the mouth is simple you can use any line for that. hair is simple its not strands of hair its chunks, try to keep the bangs 6-8 chunks only as this makes the sketch easier and cleaner use the rest of the circle as a guideline for hair so it keeps the sketches flow easy and clean. as for clothes and hair I recommend using a reference Pinterest is a great place to look up base body references and clothes designs. as for shading first put your base colors on then figure out where the light is on your character then shade where the light would create shadows with a bit of a darker color then your going to blend, I recommend adding highlights to areas like the nose, lips, top of the hair certain types of clothes that are shiny.
