This is my warm-up sketch at Geylang. I went with 2 other fellow sketchers and we sat at a coffeeshop opposite lorong 19 (= Lane 19). Geylang is Singapore's red light district and probably equivalent to King's Cross. Lots of old shophouses here. Sketching at night is very challenging yet fun. The challenge is always how to keep sketch from looking like its done in the day. More practice required.
