Now that I live in Birmingham, I've been meeting up with my friend Sammy for 'inking club' (we sit in a café and ink either our own work or each others, depending on deadlines). Last time she filmed me inking one of her sketches and made a beautiful time lapse! I've never made process videos so I've never seen my own process sped up like this.
If you're interested in my 'ink and water' technique, this shows you all the steps involved. Sammy did the sketch in 2H pencil on Bristol Board, and I used a Rotring Art Pen and Pentel Water Brush Pens.
