Shanghai flight sketch

my doodle on the way back to Kuala Lumpur from Shanghai trip.

I started with something I have in mind but in the end it turns out to be different and most of the time better ;)

An air steward saw my sketches and said he studied art too, and he likes drawing.

Surprised by his sudden appearance, I looked at him and smiled, I don't know how to response, and then I continue my drawing...
