Well...good to know you enjoyed yourself...
one would need to develop a style that you're comfortable with...only limited by your equipment that you're using...a quick example would be to try and see common touristy pics from a different perspective...from different angles...a normal pic will look interesting...having the courage to walk up and engage the subjects will reward you with nice local human interest in your pics...
I know lah...talking abt all these is easy...actually carrying out is not that easy at all...am also still learning...bottom line...heh...keep shooting and don't give up lor...heh...prob thats the only advise i can give...heh
