One thing I keep noticing is that there doesn't really seem to be focus on one thing in particular. Just from looking at that collection, it seems like you're only taking one picture of the thing that catches your eye and then you move on to the next thing. You've got a digital camera, so take advantage of that and take a ridiculous amounts of photos of one thing from all kinds of angles, with different lighting or different positions. Don't limit yourself to the norms. And above all, KEEP TAKING PHOTOS!
Cause I like them too.
