down the street

I can hear that middle guy singing! You have captured the moment and their energy so well, which is about 80% of a good 'live' shot.
There is a really nice interplay between the way the three of them are looking in different directions - speaks of a small crowd watching.

I would like to see more of these guys - the classic 'essay' - a closeup of that central character would be worth the time and effort, and those instruments look interesting too! And the fact that I want to know more says that you have already communicated quite a lot about these guys!

I think the B&W works for the more modern clothes, but that's a call to make on a per picture basis -- many of your other images live because of the colouring!

Some technical comments/ opinions:
1. I think you have your lower 3/4 dark tones too dark - lifting them makes the features of the guys pop out, without muddying the black at all.
2. I'm not nuts about a vignette on a photojourn shot. This is life as it happens, rather than a studio shot.
3. It would be nice to see the feet! Which may go with
4. A lower camera angle. These guys were a captive subject, so to drop to your haunches and get a couple of eye level shots, rather than looking 'down' on them would be quite feasible.

Getting into the habit of trying a few angle variations (and getting in a little closer) whilst shooting often pays off with these sorts of images - it can make the difference between good shots and great. And you certainly have the ability and eye to record the 'vibe' of Darjeeling. I hope that you are sending off your work to the local tourist information agency for a little more exposure!
