well you dont' line up every major detail when drawing people/organics ... you just do the major sections that MUST be lined up - suchas chin-eyes-top of the head, bottom of the ribcage, waste, crotch, knees, floor and thats all - a few light lines handles it quite well unless you want to do a top down view
but the best thing for humans/organics is to just do a side-front-back (hense the term turn-around
) you'd also often do another which is a perspective just to so you have a reference of how it should kinda look at an angle as well - as sometimes some details arn't best as precision but as a flow of the work
I pride myself that i don't kill...
well not without a good reason
