Note that all base and layer paints are thinned with water, and a touch of liquitex flow-aid. All glazes are made with Glaze Medium .
My approach is to base and shade the whole miniature before moving to layers and highlights. This is so I can get a sense of how the colours are working together and so that I can correct any painting mistakes more easily. In general, I’m more likely to get paint where I do not desire when basing and shading. This is because the layers and highlights are typically applied to surfaces that do not connect two elements. These connection points are generally in shadow so only the base and shade are applied here.
