I have been following some tutorials by Feng Zhu and he draws in an industrial design fashion that relies heavily on perspective.the artist sees and learns to draw whatever they see from all directions in a 3d state thus learning to draw from memory easier.
Drawing from memory and off the top of my head has always been an issue of mine but when i followed a tutorial along with him via video I found the method more helpful in understanding forms and objects.
I can't get a hold of Feng Zhu to ask him of any books that may help me learn. And the one book I have explains it in a way I find hard to grasp with the use of elipses and dotum lines. as per attachment. The style i wish to learn is in the other attachment by Feng In 3/4th view.
I figured I'd ask her as someone should have experience with this.. I hope.I can't afford to go to a school that will teach me this ..like feng's school. so I hoped for at least a book.
