The same ink strokes can represent multiple different objects. Add a bit of watercolor, and the possibilities are reduced.
What the eye identifies as a mandarin orange, mainly because of the color, wouldn't be so obvious without the brush strokes.
Color adds an extra dimension to my drawings.
Yet the key is to get proportion and light right, which I always do with microfiber ink pens.
Only then does watercolor (or shading) add information and help the viewer understand what they are looking at.
