Zombie's Book of Sketches

[darktiste]

Just make sure your first horizontal and vertical line are straight or else you will get fuck top stuff.If you can't even draw a square that have 90 degre angle you don't want to be going into perspective yet.Do less tracing and do more cube in 1 and 2 point perspective do alot of them like atleast 10 but i recommend doing until your tired or until you can draw them without guide going back to the vanishing point.Think like an architect you want your blueprint to be solid before you go into the detail.This mean understanding the theory.
