I'm not much of a judge of street photography but I like most of these (not so keen on #2 and #7). You've chosen good subjects and you've captured interesting expressions. #7 might work with a closer crop, at first I didn't notice that the girl was taking a selfie with her phone.
You've got an eye for a good shot. I'll look forward to seeing more.
I really like #5 for some reason, I wonder how many people here actually realize why there's a wire hanging out of the back of that radio. Nice pics, for #3 I'd say try to get at the eye level of the subject, in my experience the pics turn out to be better.
#4, if I'm not wrong is a blacksmith; I'm curious to see more of his shop and maybe him working on his craft. Again,rather than a downward slope to the subject, a lower camera angle would have helped. Really nice overall and welcome to TPF
Hey! Wait a sec! This is from near Esplanade.. You are from Kolkata!
Anyways, I'd advise you start a new thread if you need C&C for new pics. For the first one, I don't like the heavy vignetting, but that could just be me! All your photographs could use a bit of contrast boost, and the last one you need to set the white and the black points properly to remove that washed out feel it has.
Overall, I quite like your work.
