Here's a scene from 2001.
And here's some pics from 2004.



These were taken in 2008.
And these were taken today.
What do these photos show? Over time you might think things get bigger and better.
Some plants do get bigger because they have found their right place and are continuing to earn their place by looking right. An example of this is the Agonis flexuosa which I brought home in my car many years ago as a small young tree. (I have known it nearly all its life!) This tree not only looks great, but since it is near the compost it provides a handy place for possums to nest and eat dinner.
As for getting better ... I like to think that the overall design is improving. But the reality is that the garden progresses cyclically - it looks great but then something changes, and it doesn't look so great. I had a visit from a blunt speaking non gardening cousin over the summer. He looked out the window and said in surprise: "There's nothing there". I guess some people see what is, other people spot what is potentially there.
