Drawing is something I've always struggled with. I watched a video of an interview with Glenn Vilppu on the Proko youtube channel. He is a lifelong artist and was an illustrator for Disney and taught for Disney all over the world. His statement "drawing is a fundamental skill, but also an advanced skill". He also said "if you don't draw well, your painting will never progress beyond the ability of your drawing". Those 2 statements made a lot of sense to me so I followed a recommendation by @Castillo
and ordered "Figure Drawing for All it's Worth" by Andrew Loomis along with "Lessons in Classical Drawing: Essential Techniques from Inside the Atelier" by Juliette Aristides and "Drawing the Head and Figure" by Jack Hamm.
The first one by Andrew Loomis was originally published in the 30's if I'm not mistaken and was out of print for a while and is now being published again. After looking it over and reading the opening chat I think this book will be of great benefit to me and anyone who would like to improve their drawing skills of the human figure.
The second one by Juliette Aristedes comes with a DVD where she demonstrates some of the techniques in the book. I also think it will help me. It doesn't just cover the human form. In fact she recommends to start with objects before drawing the human form. Point being that the slightest variation will change the expression. Starting with objects will help hone your skills. Her feeling is that anyone can learn to draw, you just need to learn how. Amen to that!
The third one by Jack Hamm is very thin paperback. Maybe only 1/4" thick. There are a lot of small illustrations and very brief descriptions by each. By far the weakest of the three.
There is a post further back in this thread where you can download a PDF version of the Andrew Loomis book (thanks @Dencal)
I downloaded it but bought the book so I can read it and practice sketching from it during my lunch break. Enjoy!
