exposure on the fullerton building generally looks ok but on the merlion lower right highlights are blown. Probably you want to ev-0.3 or -0.7.
Just stating my frank opinion if you don't mind.
There are 3 main problems in this photo.
1. The obvious tilt to left and the perspective "distortion" of the fullerton make it look worst. Feel like things are slowly sliding down towards the left.
2. The "arrangement" of your subject and other things in the photo looks totally haphazard. Just like any form of art arrangement be it flower, still life painting, etc. there should have a sense of balance, or some sort of harmony or colour or geometry or lines or a way to draw the eyes attention. Basically, there are just too many distracting element in the photo, eg, the road sign, a human, the stainless steel guard, palm trees (are they palm trees...??)
3. Choosing where to crop the building. First the top, its like taking a photo of a person with the top of this head "chopped". Doesn't looks good. Second the sides too.
PS. I actually have a bit more comments if there is exif data in this photo.
