I can see some potential in your images and i would like to make some comments.
1) I think they would work much better as B&W images.
2) For the 1st image, perhaps you can try a tighter crop?
3) 2nd image is much more interesting i feel, again, better in BW.
From these images i see potential interest in documentary style. I would suggest you go to a good bookstore or the library and seek out books by noted journalistic photographers like Sebastiao Salgado, Henri Cartier Bresson, W. Eugene smith. Study why the images work and go out and shoot some more
Maybe my first post didn't elaborate more..I didn't go to batam to take pictures of workers..I went there on a holiday trip. So photography was not my main purpose..just sharing 2 pictures nia..
Anyway, these shots were made with an ixus i..the older model with no zoom. Hence expect no bokehs..
