This man stopped my movement

Taken at the tampines mrt, the uncle can write it upside down, clean and fast. I did time him on his second drawing, 1mins and 5 seconds for this sheet. When i found this man drawing with his feet in orchard, after 2 months i found him at tampines mrt while i'm on my way on work, and wanted to take his picture, after he drew finished, he hold it up to me first and smile at the camera and he turned to show others, donated him $5 for his clean work, his smile and his picture. Kudos to him
