![Angel Giraldez Masterclass Volume 2](http://lordsofwargames.com/cdn/shop/products/d3fce6f24ee25072828487fcb5f2cba839569169_500x500.png?v=1620595723)
This really should have been Angel's first volume, as it does offer a comprehensive study of miniature painting in terms of theory and technique. Examining warm and cold tones, the color wheel, a study of light, and then examples of painting non-metallic metals and many infinity color schemes that are applicable for many miniature projects.
Very recommended to improve: Color choice and selection, painting NMM, learning to Airbrush.
