I think of all the shots the VW is best, but a couple of friendly C&C:
1. Look at your whitebalance -- the vw looks a little offcolor
2. Use a lens with a bigger focal length or bigger aperature. Then you'll get more bokeh (item in focus with a blurry background)
3. If you shoot beyond your infinite focus, you won't get any bokeh even if you shoot at a lens with a very large aperature.
4. Your composition needs some work... Some subject matter is very easy to photograph -- if you stand on St. Mark's square in venice you would have to be a very bad photographer to not get a shot that most people would look at and go OH WOW! But when you photograph everyday objects they really need to be compelling I think -- either through use of depth of field, or perspective or sometime.
Your faucet is nice, your flower thing is kind of nice, but the rock really isn't anything special.
You might be able to find a way to photograph it into a special photo, but because it's a rock you're going to need to try harder then just snapping a photo.
