I like the abstractness and reduction to lines and shapes and colours in 4. Very nice!
However I am not too fond of your composition for the flowers in 1, too much is being cut off, and the light is extremely yellow. It must have been lamp light. Was it?
The background in Photo 2 is very busy with part of the vendor's face (mildly blurred) showing between the puppets, and a car on the left ... would have been nicer if it had been more reduced to the subject (puppets).
3 is really interesting. Like Alex is saying: it is ALMOST abstract, though it is not. I personally would have cropped it somewhat differently, I think, but since it is your photo... It's just that I find the bottom (blurred) hand distracting. That's all.
