Hey! Don't want to overload you or break your stride in Norling - that book is the priority. But as you go through it, you might like to check out on the side what Loomis says about perspective. He doesn't say much, in terms of pages. Generally, he sums up the principles with a few examples on one or two pages! Haha. In any event, you will see exactly what Norling talks about
www.deviantart.com/users/outgo…If you ever lose the link, you can always find it on my profile page in the QUICK PICKs section. Right now there is another book there, too, ANIMATION by Preston Blair. I used to have over a dozen linked directly to my scribd.com collections. But as Scribd went commercial, many people who posted their work free either took them down in protest, or went along with Scribd's suggestion to offer them for a price (with Scribd taking a commission).
