Need advice and criticism video

Please tell me, is it worth doing such a video? No sales.http://www.pond5.com/ru/stock-footage/47619259/musicians-playing-accordions.html

I'm just starting at Pond5, but I guess If there is a location
on the video, maybe is good for cultural news video also.

That's a great video. If you had model releases signed by the two men, it would be even better. Nicely shot!
