This is the Ackerman with crowquill section and reservoir mod writing sample. All this was written with one pump on an A5 sheet of paper. You can buy the Tachikawa crowquill reservoir from http://www.amazon.com/Tachikawa-Tank-Master-Comic-Pen/dp/B006CQUKDI
These illustrations were based on selected stories for the ELLE Writes competition and they appear in this month's (Nov) Elle Singapore Magazine. I liked the stories chosen. Tools used: Zig Calligraphy marker, Modified Custom 742, Parallel pen + watercolours.
