I just wanted to find out where this city hall is located. I thought that it was from Singapore but now I have my doubts. :)
Perhaps you didn't realize that having friends vote for you was unethical. Mistakes happen. However, this photo and it's 1st place finish has generated a lot of controversy. Many feel that it did not have merit for such a placement.
I can also see from looking at your profile that you've got talent. Some of your photos are quite good. You don't need to have your friends vote for you. I would encourage you have them stop and let your photos speak for themselves.
> I dont quite understand this concept of vote spiking...there are friends who take interest in photography and who are members of this website and they vote for me I know that for a fact...however..this is the last time I will enter a challenge on dpreview.
