“Drawing on the Right Side of the Brain” made a big splash when it came out decades ago, but the title made me think it was some sort of feel-good manual where any exercises would include a chorus of Kumbaya. Boy, was I wrong! It is a prescriptive and concrete guide to the physical activity of translating observation of surroundings into realistic representations, so useful that it’s in its 4th edition.  The author Betty Edwards does not claim that accurate drawing makes you an artist and she actually points out that there are many artists who cannot draw; the two are not necessarily related.  However, the ability to sketch your visions and ideas is a useful skill, no matter what your working media normally is.  If you aren’t confident in your drawing abilities, I recommend at least reading the intro and first chapter while standing in the bookstore.  Better yet, buy it, read it, do it!
