That antique seller shot is really great. Everything about it just... works.
The series is nice. Reportage style, informative, but lacking a little something. For example:
"How does it feels like, working for years in a foreign land thousands of miles away from home and family."
Why don't you show us? I don't really get a sense of how that feels by looking at that photo. Putting that emotion into the photography will help tons. But looking at photos of bored people is usually, well, boring.
I think you should also control your composition more. The picture of the old man on the tyre for example, his expression is incredibly strong but my eye can't concentrate on his face... It just darts around, and I quickly move on to the next picture. Show us what you are trying to tell us.
