There are both good and bad as photographers in Singapore.
Good: The "limitations" imposed on us make us look hard and be different (only if you chose to), in the process training our eye for great pictures. A great preparation for overseas shoot, perhaps...
Bad: Although a great preparation, once in a foreign land, very often Singapore photographers are overwhelmed by the nice deep blue sky, rich autumn colours, splendid landscapes to a point we "lost" the fundamental in making good/great pictures. This happens to me occasionally as well.
Familarity and revisit of a place is crucial unless you want to try your best of luck, hope for the best to happen when you were there!
At this phase of my photographic life, deep rich blue sky bores me to death. It has been done/seen to death. Am not a sucker for dull greyish sky either. But, a deep grey, almost threathening sky or a blue sky painted with unusual clouds works for me!
What Singapore sky is lacking is not deep blue sky but a dramatic sky, a dramatic unpredictable weather and also a good quality air (which often translates to good quality light).
Fluffy or Thundering Clouds/mist/fog make a sky or a scene different. No two clouds/mist/fog are the same which make them, a scene or a sky unique/dramatic in their own right.
All said, I surprised myself that my best landscape/cityscape pictures were mostly taken in Singapore. Familarity plays a part as well...
