Travel Watercolor Journal--- travel set idea of using a pill sorter for paint.

Chefchaouen (Marruecos) by Isabel Seidel. Urban Sketchers Spain.

Just really like this "loose" watercolor + pen sketching style. could be used to sketch humans, the school, or urban landscape. El mundo dibujo a dibujo.
