Erik - the fact that you are thinking about it and looking back over your work with a critical eye suggests to me you are evolving into photography in a fairly normal way. Your statements suggest that you are recognizing issues with your previous work that you had not been able to see before. It is a road that many of us here at CiC will recognize, as we have come down it as well.
I think the second part of your thoughts dealing with moving from a snapshot to a photograph are also an important part of the photographic journey. A snapshot, even a "good one", implies spontaneity, rather a thoughtful, planned and deliberate approach to image making. I find that there is a second issue with snapshots as well, and it the person behind the camera is too busy looking at the subject to see the whole scene. A photographer goes about taking a picture in a manner almost diametrically opposed to this approach - taking a photograph is a deliberate and planned act, where the impact of the subject, as well as the foreground, middle ground and background are considered.
My final thought is Henri Cartier-Bresson's famous quote (made in the film photography days); "Your first 10 000 images are your worst". Some people feel in the digital era, that the 10 000 image threshold is likely more like 100 000. Cartier-Bresson said "photographs" not "snapshots", so I feel that the latter should not count towards this total...
