Interesting you made the comment (further down) "the toughest part is finding good subjects." It's actually quite easy as they are everywhere, literally. The main concern is how you look at them from the viewpoint of being creative and trying to convey a message/story in what you see to a photograph. And the best way to achieve that is by considering light, angle, texture, viewpoint, depth-of-field, colour v black and white etc. This will determine the difference between a point and shoot image and one with some level of thought beforehand. A good idea is to walk around the subject (not always applicable, I know) to determine to what extent those previously mentioned issues can be best applied. Good luck
