Welcome to CS. Get use to blunt advises. They do have truth in it.
After looking at the sample shots, I think the timing you take the shot, and tripod for your camera are critical factors.
Your sample shots should be taken shortly after sunset time (not total darkness), so the fireflies' light trails aren't too long.
Lastly, turn off your flash and don't forget to share your shots!
A true photograph need not be explained, nor can it be contained in words.
Thanks for all the advice, I will post the pics at Clubsnap FB, if I can manage to get decent ones. :-)
For tripod, may I ask if the DIGIEYE brand is gd? Did a search but didn't find much info here. Am thinking to get the TR-37 at ~$30. My friend is using a Sony prosumer and needs to get one too.
and for selection of tripod, refer to the guide here
