I don't think it's very useful or even sensible to try and categorize 'street' according to whether they have certain elements that one can check off a list.
Let's see - in street, candid, message.
That's like trying to tell if one finds another person attractive by checking off whether they have certain physical characteristics. What is missing in the evaluation is whether the elements are melded together in a way that has a certain, lasting impression.
In the case of a picture that impression generally is linked to some notions that the viewer may already have about life, beauty, anger, society, etc.
Yes, this picture has some of the 'elements' and maybe we could even sketch a possible 'story' but does it have any emotional impact, is the idea portrayed in any way that is obvious except in a strictly intellectual level?
IMO, no. This is a miss for lots of reasons. The overall tones are bright, there's lots of 'stuff' in the image that doesn't contribute, there seems not be be any tension between the busker and the person walking away. The busker is involved in what he is doing.
Saying all the reasons may not add up to anything, just as listing why one doesn't find a person attractive may not. Basically, for me, there is no emotional impact.
Sorry.
