Learn new skills, explore new subjects, go to new places, read more books.
If your photos look uninteresting - there are many possible reasons, perhaps:
- composition is poor?
- choice of subject?
- wrong lighting?
- many many more possibilities.
Several responses seen are around choice of subject - if HDB is boring to you, go to town. If town is boring to you, go out of town. If things on land is uninteresting, take up scuba diving. If shooting woman is not fun, shoot kids, or find old persons, explore lighting to flatter skin tones on women, or to accentuate texture to reflect the path of the older persons.
But nothing will look interesting if one hasn't learned the basics of composition, lighting, aperture control, shutter speed control, perspective, bokeh, rendering, etc, and the list goes on. For what it's worth, I started shooting in 1978... and still learning...
Go to library and look up books on photography, and photography subject. Do you like shooting pretty women? Architecture? Landscape? Sports? Flowers? (or heaven forbids - big money lenses, camera and camera support system) Birds? Fish? Tokyo? Seoul? Iceland? Malaysia?
Or the final thing may be, photography is not for you.
