my god..this picture just screams "post processed"
you used photoshop to bump up your highlights too much. There are burn spots in the river because of that, not to mention the lights. Also, your buildings, some of them got a halo effect. Really oversaturated here.
Overall looks really fake.
Word of advice. Don't post process. As far as you know, photoshop doesn't exist...try getting the perfect shot with your camera only.
Post processing should usually be restricted to a little...LITTLE..change in brightness contrast...minor spot correction if required. Everything else can be done with the camera.
What are you training to become...photographer or digital artist?
If its the former, work more on your composition skills.
For this picture, in my view at least, you could have kept your shutter speed at 2 seconds or higher, adjsut the aperture accordingly..should come between f/8 to f/16.
Then just shoot...
I personally never believed in the rule of third, I find it dull at times, but as a beginner, try following the rules. Once you know how to use them, then you can break them.
Right now I look at this picture and I don't know the subject...do you want to show us the merlion? or the buildings? or the sky?
And I was reading the previous commments. I agree with octarine here. If you can't answer certain questions about your own photographer, then you are just another layman with a camera. People here post at clubsnap to show off their pics, and to learn at the same time. Answering questions pertaining to your photos is part of the learning process.
Of course, sometimes you click just for the sake of taking a picture.
Its alright though..you understand and you continue ahead. Thats how photography is.
Play around with the angles, realize how to look at the world through the viewfinder. And then just click!
Hoping to see better pictures from you soon.
