If you paint region by region as I do, make sure you’re aware that each individual object is part of a larger whole. The learning painter is often so detail oriented that he easily loses sight of this fact. One must constantly shift one’s focus from macro vision to micro vision and back again. These iPhone pics of my current work-in-progress (WIP) demonstrates how I paint a bit of the surrounding areas to give me a better context for finishing the more important elements.
Note: this is just the complete overpainting. There will be some glazing applied later which will add richness and subtlety to the color.
