A heartwarming video of an artist making a live-portrait of his co-passenger on a train is going viral on social media.
The video was shared by Vishnu Dineshan, whose Instagram bio describes him as a self-taught artist.
In the video, Vishnu can be seen sketching the old man from the upper berth of the train as the man sits on the lower seat across him.
The video concludes with the artist showing his sketch to the man which in turn brings a wide smile on the old man's face.
