I think he clicked photo of the cashier and then made the sketch. It was not spontaneous. I appreciate that his sketching skills are good. But he makes false claims that he made it without taking her photo.
I remember, when I was in class 12 and clicked picture of my tution techer secretly and i sketched my tution teacher for a week and it was really difficult and when I gifted my sir in teacher's day Eve entire class shocked. Even now sir hanging my sketch on his wall
Scanning, keeping in mind and drawing small small parts isn't possible. Doesn't matter even if you're clicking pictures secretly and then making drawings. Be open keep up the good work.
