same guy, resized picture hihi.

I draw a lot of boxes freehand, whats the difference between learning the same mistake and not improving, and making the same mistake so many times that you are able to identify it? I rarely do vanishing point studying and instead try to draw furniture in my house as boxes, but I mostly do it from imagination, what could I reference anyway? a cube either looks correct or it doesn't its so simple how many mistakes could you make?
