C&C per req:
1. A good idea, but some issues with the execution. First is the uneven lighting; you have very bright (window?) areas between the leaves upper right, and much darker areas lower left. To get an image like this "right" you will often need to adjust the lighting and/or positioning. In this case I suspect sitting the plant on a plain, medium-dark background, in an area where the light was more equal on all sides would have helped greatly. Additionally, The focus doesn't work for me. You've picked a very difficult subject, particularily given the limitations of a P&S camera, however, I would suggest a reshoot and try and get the area in the middle where the left and righ-hand most leaves meet as the point of focus.
2. Again, this one has lighting issues with extremely bright highlights in the window; always try and avoid shooting 'into' a window. As well the DoF is shallow, but not quite shallow enough; there's more in focus than there should be, resulting in a somewhat distracting, and rather 'busy' image.
3. Not bad at all. I rather like this one. I would suggest dropping the brightness of the floor a little bit and doing a re-crop so that the slippers aren't quite centered.
Just my $00.02 worth - your milage may vary.
