This video goes over the complex understanding of foreshortening. Well, maybe it's not that complex but it sure does seem hard to draw at times. Hopefully this helps other artist like me that constantly battle this behemoth of a task. Just remember to keep your sketch nice and loose and get the idea down first, then come back and add all your fancy lines!
Good luck to you and thanks for watching!
