This is the first "step by step" I do, and therefore I hope it is understood.
This is how I draw this type of faces, without being full profile or frontal.
I will use one of my original characters as an example:
#1 Identify the angle at which you want your face to be looking. This is identified by starting a circle with a vertical line where the nose will be located.
#2 Draw another line, this time horizontal, where the eyes will be placed. It serves to measure the height of them.
#3 Lower the opacity to the base drawings. If you want, you can merge both layers to avoid having so many.
#4 Then proceed with the eyes and nose. The distance that usually exists between both eyes is a third eye.
#5 Then I connect the chin with the end of the vertical line???
#6 Make the hair.
#7 Proceed to erase the sketch base.
#8 Paint it and add the shadow of the neck.
#9 Mark the volume of the hair with lights.
#10 Add details laik more shadows in the face -and any other that your character possesses in him-. Remember the source of light, this means where the light comes from.
Aaaand done! Hope you like this step-by-step attemp!
