I looked through all 12 pages of your Flickr account. Overall, what I see are lots of snapshots and straightforward "recordings" of things, with a lot of similarity between frames. Maybe the similarity is due to the lens you use...there just is not much "variety" in the majority of your images. Your lighting is very monotonous and uninteresting. On page 9, there are a few images that show some artistry,and are "more than just snapshots". A year and a half of using a camera is not very much time, and it does not appear that tou are doing much more than pointing a capable,modern d-slkr at subjects,and allowing the camera to do the work. It's difficult to put into words, and so many people gt all bent out of shape whenever they are given C&C, but your photos are, for the most part, the kind of images most people would make with a cell phone camera today, or a compact P&S ten years ago, or a Kodak Instamatic 126 25-30 years ago. You are not pushing the limits of anything--not of lighting (indoor fluorescent or on-camera flash), not of lenswork (limited focal lengths, pan focus,no selective focus), and not of composition.
My suggestion would be to pick up a fe books on photography and stuydy them, and attempt to incorporate a few elements and principles of design into your work. For example, look for repeating patters or line, or repeating anything, and try and make some photos that show the ability to work with repetition. Look for some small abstract segments of the world, and see i you can show them to us. and so on.
