Hi, I know that this topic has been touched upon numerously, but well... Once again here I am, confused, Let me talk a little about what I want based on what I have already done: I have finished Edwards' Drawing on The Right Side of the Brain, practiced with its method for about 3 months, Went on to Juliette Aristedes' Classical Drawing Atelier, Studied it [It was goood!] and practiced three our of it's five practices [Specifically, I've produced hundreds of hundreds of shaded 3-D Eggs, Boxes and Cylinders in Perspective, done over 20 Master copies to near-perfection, and drew over 20 lifelike portraits; It was hardwork, but fun!] The other two practices which I have not done were the Cast [I do not have any casts] and the reductive charcoal [I hate Charcoal, Just hate it!]; During this I also read Harold Speed's The Science and Practice of Drawing which pretty much confirmed the uses of my system.
I now can do portraits of good quality [I'll scan some, later] The portrait in my avatar is from the Betty Edwards era, I draw a lot better now.
About a week ago I purchased Vilppu's Manual based on recommendations here and got pretty finished with it by today, I found out I've already practiced it's basic objects and it's 2D construction area, The light and shadow parts too so they all were pretty easy to grasp, I've filled about 300 (A4-size) pages with drawings during studying the Manual.
Now, The anatomical parts in Vilppu's were not good at all, atleast for me, I plan on fixing that later; But as for now, Too many voices asked me for Perspective, I've already studied basic Perspective [that is, 1-point, 2-point, 3-point perspective] And I want to move on a little, Any recommendations?
And please, If it's an online book [Pubic Domain, I mean] It'd help pretty much, I already waved too much goodbyes to my money!
In short terms, I need a good perspective book to practice perspective Beyond 1-point, 2-point and 3-point builds.
