I used one color - sepia - to create this landscape paying attention to tonal values. I used it also as an opportunity to practice watercolor techniques: wet-in-wet, wet on dry, dry on dry. 

Materials used: 

Sepia watercolor from Holbein

Raphael sable pointed round brush no. 6

Sable brush from Pigment Tokyo (small, no idea what size; it’s Japanese brush) 

Arches watercolor paper 300 gsm
