Just a quick open-up of a typical approach I use for making stuff.
Setting some limits and fastening down the composition.
Blocking-out the main parts.
Completing the borders for different areas and sketching key flow directions.
Cleaning up the construction.
Remaining contours and edges being added as well as ground shadow locations.
Blocking-out main shadows with help of sun direction. Remember to account for light bounced off the floor.
Scribbled a basic palette as a target. Colour blocking the whole outline.
Adding colour variations as a basis for surface contours.
Blending colour variations
Adding more colours and blending, and cleaning-back some edges. Thickening ground shadows.
Colour areas being finalized before eventual blending.
Last traces of pencil marks removed. Colours merged with lighter wash.
Darker tones filled-out — Finished!
