We’ve experienced these young men live. Both you and they have great timing! The NO street performers, in general, are worth paying attention to as they take their jobs seriously. Always tip as much as you can. Great shot!
Excellent work on the mono conversion, and a strong composition. It may be worth revisiting your sharpening as there is some slight haloing around the shoulder and back of the boy. The image is really good, and warrants that just tweaking.
