I would avoid flash pictures cause it will make things look flat. Also, i would not try to put everything in the photo but focus on some details (but I'm not a pro
). Maybe try to give some depth or have part of the scene unfocus.
I like to shoot that kind of scenes with high aperture. Here is a picture of people playing chinese chess I took in Beijing last month :
Good luck and share your shots on DPS so we can have a look :P
