Stick the sticky tack on the cork and stick the dry primed miniature on it. Limiting the colors makes the figure look more coordinated, and less cluttered. Take a long look at your miniature. Choose no more than 3 colors to paint the main areas of the figure. Choose colors that look good together, usually one main color, a complementary one, and a contrasting one make an interesting combination.
Mail usually looks best in a silvery color.
Paint your figure, starting at the innermost layers, like skin and shirts, and paint out. You will get paint into areas that are high in the effort to get the crevasses, so worry about those areas last. Don't worry about painting the details at this point, just get paint on all the areas of the figure. Once you're done, take a minute break and look at the figure again. Paint the spots you missed, making sure to look under arms and in the other under parts of the figure.
