Pickup Truck Painting

I wanted to do something different with my last watercolor class, but still keep it with the fall season. I combined an old fashioned truck and pumpkins to come up with this combo.
1. I started the drawing by making the wheels, then the frame of the pickup truck around them. The back is filled with pumpkins, and a horizon line and sun are added.
2. All the lines are traced with a black permanent marker. 
3. Details are added with crayons, as with the yellow on the pumpkins.
4. All shapes are filled in with liquid watercolors.
