After that I duplicate the color layer, lock the transparency, fill the duplicated layer with white, and set it to multiply. I paint in shadows on this layer. Then I do subtle light tones above this using a Brightness/Contrast adjustment layer, and add sharper highlights on another layer (usually set to dodge or screen). Then at the end, I add in a texture overlay on top of everything, and sometimes I'll do some gradients or fills with an overlay layer to tweak the colors.
