Cropping it to just the group of three does make it more "street" but it becomes bad street! There's a *little* more interest there, but not enough.
The tight crop on just the two is a completely different photograph, and as I mull it, I like it better. There's an interesting dynamic there, I feel like one is a teacher and the other a student, but I don't know which one. This is also present in the larger photo, of course, but the larger photo has more stuff, and another easel in the background and so on.
The original crop is, to my eye, definitely street. Russ is right that it's lacking some stuff to be really good street, but I like it pretty well. If it was mine, I might print it and hang it where I can see it for a while. I think it's a photograph that might take me a year to see that it's excellent or awful, but I feel like after a year I'd know one way or the other
