Alex, it is not wild orchid. This is simply the common roadside weed, the Common Asystasia, which can be found everywhere in Singapore.
Back to your photo, I find two subjects being focused in your photo, since you titled your shot as a flower shot, I will then find that the sharp young shoot is quite distracting here and trying to draw my attention from the flower to the young shoot.
Hey, ortega, i think i took a picture of the same flower too. Just that didnt managed to capture a colored blackground (mine came out black), and colors abit dull :'( (may post on a thread later once i play around with the ps.. =X)
Yes, have to agree that the young shoot is vieing for attention, but at the same time, brings out a second dimention to the picture itself.
