Process shots for The Young Man from the East (original post). Digital painting from references, Adobe Photoshop + Cintiq 21UX tablet.
Random related art tip: One of the great aspects of digital painting is the freedom to adjust the entire color scheme of a painting very easily. Notice I start with a very dull-colored sketch, then through Overlay layers and other tweaking slowly bring in much brighter and more interesting colors. Mess with the Levels/Saturation/Whatever CONSTANTLY during your process, not just at the end. Once you have a color scheme you like, use that eyedropper tool like crazy to make sure your additional rendering includes the new colors.
