any helpful hints for sideview drawings?
None besides experimentation. Try adjusting the length of the face and angularity of the chin, not to get a perfect look but to discover what you can create.
The face should be the same length as the head.If your face is one circle than the head will be the same length as that circle. Also, try to remember that there are foreheads and not just straight lines.
draw a skull and add the face on it.
