I drew this sketch on an A5 Stillman & Birn softcover sketchbook. I used a 0.3 Uni-ball Unipin fineliner for the outlines and a Faber-Castell PITT-artist big brush pen for the border. Then for colouring I used a mixture of Sakura and Faber-Castell brush pens. Finally, I spattered some dark watercolor droplets to give the sketch a gritty touch.
