I have some drawing and painting skills but I'm far from a well versed artist. Lately I've come to believe that I may have "missed a step" in my hodge podge self-training and that its holding me back. I want to rectify that.
Therefore, I am going to go through a fundamentals curriculum. In order to find the right one (or several) I'm reading, skimming and scanning my way through everything I can get my hands on.
Please recommend (link when possible) your favorite books and tutorials which assume that one is starting from ZERO. To say it another way, I'm looking for pre-figure fundamentals. Seeing, measuring, modeling, etc.
