Wu Heng 无痕 written with Sailor fude nib fountain pen

Doodled this with Sailor brand fude nib fountain pen while my kids were playing in Singapore's Toa Payoh Safra Indoor Playground... Lol... Copied the words Wu Heng 无痕 (meaning... Without A Trace) from www.juntianfang.com Wu Heng is also the name of a famous guqin made by Maestro Wang Peng.
