Hi Jewel
Shots of street buskers are not always easy. We feel intrusive, and they are there for the money.
This shot loses a bit of impact because he is centered, you can't see his face, and there is a bit too much unecessary stuff in the frame. It might set up better in a portrait orientation.
In the future you might try listening for a few minutes, applauding, then dropping a buck (canadian

) into the dish, and then get in a bit closer, wait until he is not posing, and get the shots you want. Just a thought.
