I agree especially with hand drawing that perfection can be boring. The look of perfection is rather sterile looking while we can find character in many imperfections of a drawing. For example shaky lines, divets and yes by not having proper perspective. Think of children’s drawings when they first began to use the pencil. Their drawings are rather scratchy and quite loose in their lines and yet can be very minimalistic. Where as a seasoned and talented drawer or even a computer can make the same drawing as the child’s drawing with more precision with straighter and smoother lines. It could come across as being rather flat where as the child’s drawing could give off more vibrant appeal.
