You are doing okay for the early going. Your photos seem to have good color for the most part, except where the lighting is high in contrast, like the man against the window, and the new mom with grandma's little doll on her lap--in those, you've allowed the highlights to burn out--but, you've managed to keep the lower values looking good, so, that's a plus.
I think you do as reznap stated, have a good eye for subject matter. Your photos have a sort of old-fashioned thematic directness...kind of a hard quality to describe...snapshotty, but yet, more like from the olden days of photography where the camera was "brought out" to make a pho-to-graph, as opposed to today, where somebody whips out a cell phone, snaps a shot, and then checks their text messages...
