I'm not trying to say you're work is bad (it's pretty good, actually) but a lot of the pictures you've taken are snapshots. In my eyes, there are two types of photographs, pictures you would use in newspapers/magazines or just memories you want to preserve, and pictures that would be considered art. Snapshots are used in journalism, where as a person who photographs art "creates" the photograph (through posing of people objects, lighting, and camera angle, photoshop, etc.). I'll give you an example from some pictures I took.
Snapshot:
These Two are heavily photoshopped, but I still wouldn't consider them art, mainly because I had no control of the environment they were in (no tripod either).

Created Photograph:

Photoshopped example
Object posing, this isn't a great example, but I couldn't find any of my others.
Camera angle and lighting
I guess the question I have is, are you looking to take pictures as an art form, or as a form of remembering an event?
